So my good friend tried to tell me this morning i might not be as far along as my app is telling me I am, because she tracked her period and got pregnant 8 wks ago and was bleeding so she went to doctor and the doc said the baby is only measuring at 6 weeks. She said they start it after ovulation and she ovulated 4 days late. Still doesn't make any sense to me! The first day of my last period was July 30 and I ovulated on Aug 18 and all my apps say I'm 5 weeks and 2 days. My friends saying I might be a week behind cause I ovulated the 18 and not the 14! Doesn't make sense again because they start counting the first day of your last period. She said they also didn't hear a heartbeat and they are waiting to see if she miscarried. She tracked and planned her preg as well and how is it possible she off two wks and her apps?
