Can't catch a freaking break!!!!

So my lack of CF lead me to try preseed this month. Everything was going as planned: ovulated (confirmed by OPKs) BDed entire fertile week, using the preseed! And now I think I'm getting BV as a result of the preseed which alters the pH of the vagina to make it more safe for spermies. Sonofa..... Ugh I just want to SCREAM! After googling it I found this is not uncommon for women like myself who have a "sensitive" vagina. Anyone else feel my pain?!
