Could I be pregnant...? Stopped BC pill...

So I got my period on the 28th of aug 2019. I had it for 4 days until the 31st of aug. A few days before Thursday the 22nd of aug I stopped taking my BC pill and started having unprotected sex on the 22nd. I had unprotected sex every day, sometimes multiple times a day, before I got my period and during my period. 😬😬

The bleeding stopped completely on the 31st. But the last few days, the 3rd and 4th of September 2019, I’ve been getting light pink on the toilet paper when I wipe and today I got a chunk (small clot 🤢)of light pink when I went to the bathroom...could I be pregnant or....?? It’s too early to test 😭💔I’ve never experienced this after my period soo idk. Sex stopped on the 30th.

I’ve been pregnant one other time but didnt notice until I was weeks in and took a test just for fun. I had clotting during that pregnancy. Any advice or opinions?

Thanks !💙💜💙💜
