A few days after my period (this was about 5 days ago) my fiance and I had sex. The condom broke and he ejaculated just outside of me as he pulled out. I was fine for a few days up until about three days ago. I've been feeling very nauseous normally around 11pm. I've started eating a lot more than what I usually do. My back has started to hurt and I've began to become short of breath very quickly. Earlier today I had a very painful shooting pain in my lower abdomen which went done into my groin area. My partner said I should wait until my period is due to see what happens and then take a home pregnancy test, but I thought it would be worth asking on here as well. Sorry if this sounds stupid, I don't really know much about pregnancy and things like that.
