Hella confused

So my period hasn’t came for like 5 days I think and I’m supposed to have them and for like two weeks I’ve been feeling sick and vomiting and then I get really hungry all the time and my preggo bestfriend thinks I’m pregnant from those and other symptoms I’ve been having and it confuses me coz my ex (last person I’ve been with) always pulled out but we have had a few close calls of being too slow of pulling out I guess you can put it and my bestfriend has gotten me to take a preggo test which came out negative and I took one at the doctors before that one which was also negative but I’m just so confused with everything I just need a little insight rn (sorry for not punctuation cbf)
