Mam! I had protected intercourse. My periods was due on 27 of feb but somehow it got delayed and came on 4 march but this time the blood flow was less than normal and colour was red. But from 4 day the colour became brown and today is 6 pain is on and off so is the blood and the colour remains brown! is there any chances of me being pregnant? And is it normal to bleed brown colour and for 6 days and having less flow.
