Implantation bleeding

Honestly I’m probably just paranoid because I had a baby just two months ago and really what are the odds? We’ve had sex four times since the birth, the first two times with a condom and the last two times no condom, pulling out. Yes I’m aware it can still happen, but what are the chances? Not high.

The first time we had sex without a condom was 11 days ago, the last time 4 days ago. I’ve already taken two pregnancy tests (the 88¢ walmart ones) in my paranoia and both were negative of course (one yesterday, one 3 days ago).

I haven’t gotten my period back yet either, but this morning I wiped and there was pink/light red blood. Put a pad on and tonight there’s only brown discharge in it, but when I wipe there’s still that light red/pink discharge.

No cramping or anything like that. I’ve never gotten spotting or brown discharge before my period in the past although I know birth can change it. I’ve never experienced implantation bleeding either with my previous two pregnancies.

Y’all I’m scared, I really don’t want to be pregnant right now and trust me I’ve learned my lesson about not using condoms. If I haven’t gotten a real period by this weekend I’m going to test again but maybe you guys can put my mind at ease? What do you think? Also, normally with my period before I’d get cramps/stomachaches the first day of it.
