Dreaded TWW!

I'm officially on my TWW. This was my 3rd month on Clomid (2nd month on 100mg) and I got my positive OPK on CD 14 (pm) and 15 (afternoon). Today is CD 18. This is our first month of doing pretty much everything we could to make it happen! Clomid, BD, Pre-Seed, etc... Praying for a sticky bean! Anyone else on their TWW? How long have you been trying? We are 14 months into this journey...
