NEED OPINIONS!!

I’m on the pill and on the 5th I had unprotected sex and I think he came in me(I missed my pill that night) I started spotting on the 8th(cd 16) and it’s not at all like a period. It’s light spotting, just enough for a little pantie liner. It’s mainly brown, light pink, or dark dark rusty type red and absolutely NO clots. I had very very dull cramps in my ovary area for a couple hours on the 2nd day of bleeding, but they were barely noticeable. My normal periods are a medium flow and bright red with a decent amount of clots and I have terrible cramps. The bleeding lasted 6 days. Since I’m on birth control my periods are very regular and never early or late. When I started bleeding I wasn’t supposed to get my period for another two weeks. Today I had clear and sticky cm, which is suppose to mean you’re fertile but I can’t be, or I’m not suppose to be since I’m on bc, and I haven’t seen cm like that since before i was on bc. I’ve read so many things about implantation bleeding and that it can only happen 5-10 days after sex and that it only lasts for 1-3 days but I’ve also read a lot from people saying that they had implantation bleeding 3 days after sex that was heavy and 7 days long and they ended up being pregnant and just all kinds of different experiences with it. And I also know that implantation bleeding only happens in 20 percent of pregnancies. I really just need some people’s opinions. I would blame it on me missing that pill but I’ve missed before and nothings happened like this. I would also try to blame it on the sex but it wasn’t all that rough and he’s average so it couldn’t have been that either. I could also blame it on an ovarian cyst rupturing but I don’t really have a history with those and bc is suppose to prevent those and I didn’t have the pain to indicate that that’s what it was. My period is due in about 8 days I’m sorry that this is so long 😅 but any opinion would be greatly appreciated. And don’t worry, I know some of you may want to jump on me for missing pills but I’m not all that worried if I am pregnant. I would honestly be pretty happy because I’m in a good place for it. I’ll take whatever god wants to give 😁
