I thought i could possibly be pregnant, here's why. All last month i wasn't taking my birth control pills on time. I had unprotected sex on the days i missed two pills. I did happen to make them up. But i missed pills in the beginning of the pack which is the most important. I was still taking my pills, but i would take them about an hour late. (Don't think that affected anything.) Well after missing the pills and having unprotected sex, about like six/seven days later i had pink discharge that lasted for a few hours. Maybe three days went by and i had it again for a few hours. I've never had pink discharge before even from missing pills. And i didn't get my period, i just had brown spotting from the placebo pills. I took about two pregnancy tests but of course i could've took them early cause of worry. The first was negative. The second i don't think i took right because it fell on the ground for a few minutes and i didn't know they were supposed to face up. But the second one, while i was taking it it showed two black lines at first. But i guess that was just the test working. Then it was one red line negative. It's only been about four weeks so I'm not even sure if it's accurate. Should i take another test? And also this weekend i had like a brown long string kind of like a clot come out of me. Idk any advice?
