I am worried I might be pregnant. I've been with my boyfriend for 6 months and about 3 months in he started to finish inside me. I was worried initially but after nothing happening for months on the pill and taking it properly I kind of stopped worrying about him finishing in me and started to enjoy it. Recently my boobs have been really painful though (this never usually happens)and I feel really exhausted and have alot of heartburn and stomach trouble. I am 11 days into my pill packet. Hes finished inside me about 10 times in the last few days and I know I couldn't be pregnant from that yet but from a few weeks back. I feel like I'm ovulating rn and I shouldnt be. What is happening?

Tl;dr wondering if anyone got pregnant while on the combined pill when someone frequently finished inside you
