Abnormally Light Af After Bcps And Ttc

Ok, I stopped taking the pill in june. Since then, my cycles have been fairly regular--every 26-27 days. I am ovulating since I am charting my bbts and have gotten the temperature shift after ovulation. However, all my periods have been quite light for me. Last month it was a little heavier but still fairly light. I had one day of medium bleeding then it went to light/spotting. I only needed tampons the first 2 days (and lite tampons the second day). Then just pantyliners after that. My periods are fairly long--last about 6-7 days but after the 2nd day, it's almost all spotting.

I was definitely not like this before I was on the pill. I had a couple days of heavy bleeding, a couple days of medium, then a couple days of light.

So i'm wondering--do these light periods affect chances of pregnancy?

Also, if anyone here has had light periods after being on birth control, how long did it take for your periods to get back to normal? I'm 7 months off the pill and my periods still aren't normal!
