I'm 21 years old - and the last I've had sex was in March with the boyfriend. From the month April till now, my periods have been getting scantier by the month.
My periods used to be 3-4 days long, with a heavy flow. And ever since April, they have been so light. It used to go 2-3 days - but for the past three months they've been 1-2 days. It doesn't seem like my period anymore. It's more like spotting.
(Also, I come from a strict family, that doesn't know I am sexually active. I can't go to the doctors without my mother hovering as well)
