Am I pregnant?

Ok so I’m barely starting ovulation today but we have been having sex every day I’m novemeber with the exception of the week that I was on m period. AF isn’t due til the 20th but for the past two days ive cramping and nausea. I threw up lastnight and this morning the smell of bacon mad me vomit. I took a HPT and it was negative although my sister said might be to early to test. So anyway my question is are these signs of pregnancy or am I just sick
