Not sure what to think ..

So I had a period this month but it like idk almost wasn’t the same .. and I did have sex multiple times on my period when I was just barley spotting . Yesterday I was barely bleeding and it was pink and very light . Now today I’m like super sick and I was yesterday and my vagina and uterus almost just feels weird ... like something is up ... past couple weeks I changed my mindset and stoped “trying” hoping I would just get pregnant without thinking about it or trying but now I’m just having this gut instinct I haven’t had before ... something is telling me I may actually have gotten pregnant after I stopped really trying and changed my mindset . What are my possibilities to be pregnant even if had a “period” ? Seriously something is up ladies , I just know it .
