Pregnant or just stress😖

I've been living with my boyfriend for 7 almost 8 months now and the other night while I was on top he started telling me to stop moving but I couldn't. He pulled out but I'm worried he didn't do it on time because I've been having symptoms like: severe headaches, cramps, bloating, really bad mood changes, also I found a lump in my boob. Anything will help if anyone has any advice. 🙊😔
