Sex Drive...?

Kristen • My amazing husband and I have been married for 6.5 years. We are currently trying for our precious miracle. ❤️?
I've been trying to concieve for 3.5 years. I have a feeling, well I have faith, that our miracle baby is coming very soon!!??
 Anyways... Every time (about a week before and a week after) AF comes... My sex drive is crazy! It's really weird, lol. Does this happen to any of you ladies too? What does it mean? Or does it mean anything!? Lol.
 Glow says I'm fertile right now and have a pretty high chance of pregnancy... Tomorrow is my highest chance. 
​Also what is the best OPK to buy? I've never used one before but would like to start. :) Thanks ladies!
