I've been on HBC for years, but three months ago switched to pills (from NuvaRing). I'm on Tri-Sprintec. As I entered the second week of my pack this month, I started noticing brown discharge - it's actually brown, not really reddish brown. It's super-light, and has been on-and-off over the past 5ish days. There has been a *tiny* amount of redness/pinkishness, but I think that might be more due to irritation. I've also had occasional sharp pains in my lower left abdomen. I have a history of ovarian cysts, and my mom and grandmother have had such a bad history with them that they've had their ovaries removed. My question is, since I tend to get paranoid about pregnancy (I'm still in college), do you think this is implantation bleeding? Or do you think it's something else, like a recurrence of cysts or some kind of infection? Is this something people have experience with while on Tri-Sprintec? Really, I just need someone to set my mind at ease. Thanks!View Thread
