You are in a difficult place. We can certainly try to reassure you that exercise isn't going to be responsible for either your negative pregnancy test or a miscarriage but if you are going to worry nevertheless, that is a problem. We all have brains and we have to live with them. A healthy lifestyle is more likely to reduce the chances of having a problem in pregnancy. Regular aerobic exercise can also increase endorphin levels, which can also just make you feel better. I would begin training for a marathon if you have not been exercising at all but a moderated exercise program or maintaining one that you have already been doing is absolutely fine and encouraged. If a low impact exercise program would make you worry less then there are actually a lot of options including cycling, fast walking and swimming. You might also consider yoga. Focusing on nutrition can also be important for some patients with PCOS, Good luck... Dr. WalmerView Thread

You are correct that concerns have been raised about a possible link between vitamin B12 deficiency and both infertility and miscarriage. However, there has not been a great deal of research in this area.
Vitamin B12 deficiency leads to a type of anemia called megaloblastic anemia, which is potentially problematic in a pregnant women and could lead to problems with her developing babies growth and also to a vitamin deficiency in the unborn child. This is an issue that you should address with both your gynecologist and probably an internal medicine physician to correct the condition before you attempt to conceive again.
If you have access to a medical library, here is a review article that you might want to look up.
Effects of folate and vitamin B12 deficiencies during pregnancy on fetal, infant, and child development. [Review> Molloy AM. Kirke PN. Brody LC. Scott JM. Mills JL.
Food & Nutrition Bulletin. 29(2 Suppl):S101-11; discussion S112-5, 2008 Jun.
The FDA has also prepared a nutritional guide for women who are pregnant or planning to conceive that you may also want to look at as well.

Good luck.

You would not expect to have an LH surge if you are having in ovulatory cycles. Step one is to try to figure out why you are not having ovulatory cycles and step two would be to begin therapy to correct that. There could be both health and fertility consequences of not having regular cycles so working with your primary care physician is a great place to start. He/she will consider age, thyroid status, ovarian reserve, length of time that you might not have ovulated, etc. Good luck! Dr. WalmerView Thread
