rabab

Hey, i had my baby girl on the 17 september 2018. The thing is I DID NOT GET MY PERIOD until the 31 of december 2018 that is normal cause thats what happens after giving birth. But befor i got my period on the same day i had sex with hubby then my PERIOD CAME DOWN. My period lasted for 4 days. My problem is that i was supposed to get my period 2 days ago and it hasnt come. COULD I BE PREGNANT????
