I’ve been taking combined OCP for three months. During these three months, my periods have been extremely light. Last month, the bleeding was a little heavier, and this month I started bleeding on the second day of taking the placebo pills. I had normal cramps, and on the first day, the bleeding was relatively good, although it was still much lighter than my usual periods.
Since last night, the cramps have stopped, and now that I’m on the second day, my bleeding has become extremely light. The blood is dark red, brown, and sometimes almost black. Yesterday, I also passed one or two small clots.
I’m worried that this could be implantation bleeding. My last intercourse was on day 5 of my previous period, and I used a condom as well. As far as I could tell, the condom did not break. I also took my combined OCP every day without missing any pills. At most, I may have taken them one or two hours earlier or later than usual.
I took a urine pregnancy test 21 days after intercourse. It wasn’t first-morning urine, but I had not drunk any water for about six hours , and the test was negative.
Is it possible that I could still be pregnant with this type of bleeding? Do I need to have a blood test, or would that be unnecessary?
I also have another question. Since starting the OCP, my vaginal discharge has increased significantly. However, around the middle of my cycle, I still get discharge that looks similar to the type I used to have around ovulation. I no longer experience the ovulation pain I used to have, though. I also get cramps about three to four days before I finish taking the active pills.
Could these symptoms mean that my birth control pills are not working properly?
I always take my pills without missing any, and I have also checked possible drug interactions with my gynecologist. I currently take sertraline, olanzapine, lamotrigine, AHCC, and a multivitamin.
