1 Day Period & Infertility

Cintia
Do anybody with a one day period has gotten pregnant around here? I basically just have flow for one day + 3 days of spotting. It became that light after the pill, but I came off it 2 years ago. I haven't got pregnant yet and I am wondering if light period has something to do with it. I am very regular though, have my period every 28 days like clock work. Anybody with similar period and successful to get pregnant? 😞 thanks
