I'm on day 33 of my screwed up cycle. Last cycle I ovulated on day 31, so I thought this one should be similar. I've been doing opks since day 11 LOL. I ran out of the 20 I bought on ebay so I had to get new ones! I had a very dark line on day 18 but not quite positive. The next day it went back to being light. Yesterday again it was getting pretty dark, I'm thinking this is it! Today, light! Ugh! What is up with me, ovulate already LOL I'm trying to laugh it off but it's getting disappointing. At least I have two more weeks of being with DF before I have to go back.
