Dr. Smith, I came across this from fertility friend.com. I hope it helps.
I work as a flight attendant and as a result was going crazy about how to accurately chart my BBT. I got this tip from www.fertility friend.com. I found it very helpful too.
How can I chart my BBT if I work shifts?
It is not impossible to take your BBT if you work shifts, but it will be more challenging. Take your temperature at the time you wake up when you are most likely to have had the most sleep. Be as consistent as you can. On your days off, take your temperature after you wake up as well, even if it is at a different time. Make a note on your chart of changes in your waking schedule. You may take your temperature in the afternoon before you go to work if that is your usual waking time and the time after which you are most likely to have had the most sleep. It is not useful to take your temperature when you are already awake and active.
How can I take my BBT when I am traveling?
If you travel within your own time zone, just keep on taking your temperature at the same time. You may notice a slight fluctuation if the climate is warmer/colder but this should not have a huge impact on your chart. Make a note in the notes section that you were traveling so you can explain unusual temperature patterns.
If you are traveling to a different time zone, the disturbance is usually only limited to the day of travel and the day after. Keep taking your temperature as before, using the same time in the local time. We recommend not adjusting any temperatures, but again, make a note of the circumstances. Unless you are traveling right around the time of ovulation, you should still be able to discern your pattern. When BBT is less reliable because of such a special circumstance, pay extra close attention to your other fertility signs to avoid missing a potential fertile opportunity.View Thread
My husband and I decided if I don't get a BFP this month, we'll TTC like bootcamp lol.. So today we're off to buy a thermometer, OPKs and I'm already on Folic tablets and Ovacare supplements, no alcohol, yoga 3 times a week lol..we mean business this month I'm seriously chatting too View Thread
Thank you.. I plan on getting an OPK if I dont get a BFP this month. Temping is tricky because of my varied sleep-wake cycle. My cycles were on average regular before. The irregularity has however become more apparent since the miscarriage, seemingly increasing in length with each month. My last 4 cycles since Jan have been 31,24,26 & 38. I'm now CD37, no AF yet and just got a BFN 2 minutes ago I do however have tender breasts and mild cramping for the 4th day running.View Thread
Omg Chelsea!! So happy for you!! It's funny how excited I get when someone gets a BFP! It's like they give me a little hope.. You go girl!!
Just saw your post today about no symptoms n thought, oh, she's just like me! CD36 now, AF should have come 5-8 days back..well my cycles are a such a mess nowadays I don't know how to predict AF anymore lol. Last cycle was 38 days. The only signs I have are breast tenderness and cramping for last 3 days.
I'm really holding back on checking until 2 weeks pass.. So excited as each day goes and no AF..really hoping for a BFP like you! ))View Thread
I'm 32 and my husband is 33. I miscarried at 8weeks pregnancy in Dec. We weren't even TTC at the time but it was very sad for us because we and both our families were all so excited about plus this would have been my mum in law's first grandchild Soon after we resolved to TTC which we've been doing for 4 months now..
My husband has been very sweet and understanding but soon intercourse on a schedule, and the coming of my periods started to get to him. I know it's not been long but having got pregnant so easily previously had raised our expectations too high I guess.
I started a home fitness exercise regime which I did for just one week but my cycle shot from 24-27 days thereafter to 38days! So I panicked and stopped. I've been gently coxing him to get a sperm test done but I sense his hesitation perhaps because his older brother of 40 has no kids due to a sperm count issue. He keeps feeling it's too soon to do so, that we managed before so it's not a sperm issue etc.
We're trying to keep hope alive but at the same time the waiting is no cup of tea View Thread
Thank you Dr. Yvette for your very helpful responses. I read everything!
I am a flight attendant with an international airline and therefore have very irregular sleep cycles eg in the last 6 days I just cross crossed 5 different and very varied time zones! In December I miscarried at 8weeks due to a blighted ovum. The doctor mentioned that it could probably have been because my pregnancy hormones didn't kick in properly.
I have read that they are produced depending on the rising and setting of the sun (circadian rhythm).. We've been TTC for 4 months now. My cycle has been highly irregular ranging from 24-38 so it's really tricky to track my fertile days. I am currently CD34. Last cycle lasted 38 days so I'm not even holding my breath here. I have mild cramping for 2 days but no spotting. I'm just wondering, could my job be affecting my conception and pregnancy sustainability chances?
Secondly, how do I know if I'm not ovulating yet I have periods?
