I m suffering frm irregular periods since a year now.I had protected sex on may 4,missed my periods,so I did a home pregnancy test twice after my due date,with abt 4 days interval in between,it was negative both tyms.I went to dr n she prescribed me primolut n for 5 days,which worked n I got my periods on may 30..i lasted usual 5 days,bt bleeding was a little lighter than usual.. this tym also my periods got delayed,,can I still be pregnant?when should I expect my periods?
