Pcos and pregnancy

Kathryn • PCOS 🙄 TTC baby #1 👶🏼 Bi 😝Milo 🐱 Binx 😺 Engaged 💍

I have PCOS and I have very irregular periods is it possible for me to still be able to fall pregnant? I’ve felt “off” for the past couple of weeks... I’ve had very light pink spotting (I never spot), back ache, heavy boobs and very bad heart burn. I’ve done a couple of pregnancy test and had vvvvfl but a digital was negative..... is it possible for it not to come up till later? Has this happened to anyone else with pcos?
