Anybody else have PCOS? How common is it to get false negative after taking a pregnancy test? I am 4 days late and I took a pregnancy test last night but unfortunately it was negative. I scheduled an appointment today to see my doctor. I’m just so confused, my period has been pretty normal except for January when it was 8 days late but I had not had any sex in 6 months. Got my period in February right on time but this month...NOTHING! Any information would be great!
