Your menstrual cycle duration is disturbed, so are the quantity of it and the nature of the bleed. You have also taken emergency pills twice in a single cycle.
My suggestion to you -
1. Do a home urine pregnancy
test by yourself and check if you are pregnant.
2. You need to get an ultrasound
scan of your pelvis to look for the uterus
, ovaries and their present condition. Please do consult a Gynecologist about this.
3. We have to rule out so many possibilities here apart from pregnancy like PCOD, Missed abortion
, incomplete abortion
I hope this helps you.
I wish you a speedy recovery.
