My period was supposed to start the 7th. After having my child, my periods have matched up pretty well and usually only last 4 days. Me and my husband started the “if it happens, it happens” about 2 months ago. So there is a chance of pregnancy except I tested on the 7th and it was a negative but still haven’t started my period. And I’ve also got sore breast, I’m tired, and very light cramping! Help😩
