Could I be pregnant ? TMI

Paige • Mum of 2 beautiful babies 👶
I'm 15dpo, AF is a day late and still showing no signs of arriving! ( normally get extremely bad cramps and normally AF comes first thing in the morning as periods are normally very regular since ectopic ?)
​For the last week and half have been getting very mild cramps and have been  Extremely constipated however this morning have been to the loo about 7 times already ! 
​Also have been feeling extremely sick the last couple of dAYs. , could I be pregnant or just late AF ? 
​Have been extremely careful as only got go ahead go try again from ectopic couple of day ago.
