Can anyone give some advice I’ve had regular period since I was 14 I’m now 20 I’ve always used apps to track my period and they have always come bang on the date it’s due. This month I’m 8 days late I’m sexually active but use protection so panicked thinking it could have failed (not trying to conceive) and took 2 pregnancy tests and they’re both negative. I have no pms symptoms like I normally get just incredibly bloated and exhausted I’ve had slight twinges of sharp pain in left lower stomach that come and go shall I go to the doctor for this or can this be stress related it’s very new to me because of how regular I normally am😞
