Possibly pregnant?

Obviously a test is the way to know for sure but I’m just asking about symptoms. I have randomly started craving kiwis which I’ve had like twice in my life several months ago, my lower abdomen is a bit hardened, my fiancé had his ear to my lower stomach and heard a beat that was different than mine (I’m really small), my nipples are sore and darker and pressing on my boobs hurts a little and I had a bit of a twinge on the right side of my lower abdomen a few days ago. I swear I got a really faint positive yesterday as well. I’m going to retest in a few days. Thoughts?
