AF is NOT due March 21

Tori • Mom of 2 girls and a boy 👧🏼👧🏼👶🏼 and one surprise addition on the way!
So AF is not welcome on 3/21! Yesterday was the start of my fertile week and my husband and I had BDed twice this weekend and yesterday. I've been having more vaginal pain then normal.... is that weird? It doesn't hurt when we are doing the deed only awhile after or while I'm just sitting around. Anyone else have this? 
P.S. baby dust to all!! 👶
