So i havent starter my period and today when i did a pregnancy calculator to see where i would be in my cycle it said 4 weeks and 1 or 4 weeks. I havent started my period which is every 30 days and im suppose to start it in March 1. I have been pretty regular so im nit understanding how i can already be 4 weeks if my period doesnt start for another 2 days. I dont feel any cramping no signs or anything like i did with my first pregnancy. Maybe i need to stay off of google. I tested at 10dpo but got a negative and I havent tested since. So i will be testing today. Wish me luck.
