2 days late!!

Mercy • I'm 27 years old and me and my husband are expecting our 2nd baby in March. Our daughter is almost 2 and we are excited to be giving her a sibling!
So the app always says I'm going to start me period a week later than I have been. I have been expecting my period to start along with my close friend who is on birth control and I normally follow hers just a few hours after she starts hers. I am now 2 days late and crossing my fingers!
