Advice

So my period is always on a schedule and this month I am officially about to miss the whole month . I took 3 cvs pregnancy tests and they have came out negative.

The thing is I do get nauseous more, my boobs get tender, I’ve been feeling bloated, etc .

What do you think this could be ?

I will be going to the doctor in mid June as that is the earliest they would take me .

See the thing is I was on sleeping vitamins to help me sleep but I know the packaging says to not take if pregnant .

Not sure if I should risk still taking them or not .
