So I am trying out opk's this month. I am a bit confused. I have been checking my cm and it was most fertile, basically ewcm, on tuesday and wednesday of this week. Which would make sense because I should have ovulated either yesterday or today. However, I have been using an opk twice a day since monday and it never showed a lh surge until this morning. What is that about? Shouldn't my lh surge have been earlier? I guess I might be ovulating late, but my cm is pretty dried up today. Also, my husband and I attempted to bd last night and my left side hurt so bad inside that would could not continue. We tried a number of positions, but they all hurt. This morning it still hurts. We bd'd the night before last, so I think I am okay until tonight, but do you think it is my ovaries? Any help would be great!
