Insight please ☺️

I need some insight im hopping you wonderful ladies can set my mind to ease..

I’m 4 days late, I’ve been one day late before but, nothing like this.. I started tracking my period back in feb cause I would always forget cause it’s always around the 27th of the month...

Certain food smells turn me off, I vomited the other night, I feel off.... normally if I’m pregnant I vomit it’s like a instant sign for me but last time that was 6 weeks in .... so I took a few tests all come back negative...

According to all the app etc on my phone I ovulation was around 13th I had sex 12-14th...

I have 0 period symptoms normally I’ve very crampy very moody... and I know 100% it’s comming so far I’m non of it...

But if I’m this late and I am pregnant shouldn’t I be getting positive tests?

Thanks 😊
