So I've missed my period for two months now . Have been sexually active with my partner. I went. To the doctor a year. Ago & he. Said. I had PCOS but I don't. Think he. Was. Right how do you know for sure he just really did a patsmear test & told me. I did a Urine preganacy test came out negative. I went too doctor today for my anual check up and. Told. Her. What was. Going. On . & I wanted to confirm if i really do have PCOS so they did blood work. Plus they did another urine. Pregnancy test it came out negative. Blood test still not abaliablee what are y'alls thoughts ? Or opinions
