Quick Question- Preggo or not!?

My boyfriend and I have unprotected sex all the time. Sometimes he pulls out other times he doesn’t on the 24 of August we had unprotected sex and he didn’t pull out.

My period is late by 9 days, but it also is not regulated. It’s been 2.5 weeks since we had sex and he didn’t pull out and I’ve taken a pregnancy test and it’s come back negative every time.

I’ve been moody lately, just simple things piss me off, and I get nauseous occasionally but my boobs haven’t changed at all, I’ve had some cravings but nothing major just “feel like” eating certain things type of craving. I’ve had headaches but nothing crazy and not that often.

I’m just not sure if I am 🤷🏾‍♀️ should my tests be coming back negative at this time or positive?
