Is it possible to ovulate on birth control? Last week, exactly two weeks before my expected withdrawal bleed I felt like I was ovulating. I was having pelvic pain and breast tenderness- the breast tenderness is still there now, a week later, but it has decreased. I also checked my cervix and at the onset last week, it felt low and open and there was a lot of white mucus which is a change from before. Just wondering if it could be because my low dose birth control isn't working like it should (i'm on Lo Loestrin FE). Btw I take my pills everyday within half an hour of each other and have never missed a pill- The only thing that did change is a supplement that I started taking. Last week from Mon- Thurs I started taking psyillium husk before going to bed (as a fiber supplement), about 15/20 mins after taking my pill. The pharmacist didn't tell me that they could interact and now I'm reading that the husk could have delayed the absorption of the pill. I started feeling the cramping/pelvic on the Friday after, I did however not have any bleeding. I'm just wondering what's going on because I've never had mid cycle pain like this, and my breasts are still very tender. If it's pregnancy related, would a test be accurate by now? Also, I've heard that psyllium husk has soy which has estrogen, could it mean that for those few days my estrogen levels were increasing? Please advise, thanks.
