There is no way....Right???

Megan
I had a miscarriage...
Got a negative hpt July 4th (could have been negative for a solid week as I was testing weekly waiting for a "zero")
BD twice July 4th
My "period" came July 5th-6th
Been having headaches the past 3 days and noticed my nipples were extra sensitive yesterday and today my breasts are fairly tender
There is no way I could have gotten pregnant and still had my period right? I mean the egg would have been shed at that time correct?
I'm too old not to know this!
