So lately for the past two months, my period has been really light and only lasts about 2-3 days. I’ve been on birth control since November, and I’ve consistently gotten it during the placebo week on either a Wednesday or Thursday. However, for the past two months, my periods have been really short, but on time. I’m sexually active and I’m a bit worried. Is this normal while on birth control? Did this happen to anyone else too?
