7th month TTC

Whitney • Proud mom of 3 year old baby girl and baby boy due in December.
DH and I just bd'ed the day after AF was about to start. Went to wipe (tmi I know gross sorry) and AF rears her ugly head again!!! Geeeeze! Now I'm bawling crying on the couch!!! I don't understand what could we be doing so wrong?? We have a 3 year old who we had no problem conceiving. Someone told me that there is a procedure that flushes your tubes out. I don't know where to start I thought by now I would have gotten a BFP!!! :(((
