My last attempt before I decide to seek a doctor. I had the mirena removed April of 2014. After that DH (31) and I(26) had ttc for 6 months and bfn each month. Temping, opks, cm check, cp check, prenatal vitamins and timing BDing. Since then I haven't been trying but not preventing, only seriously ttc every few months. (Too stressful) I have a very active sex life with my husband. I have a usual cycle of 28-31 days and ovulate about CD 17. Like clockwork. Yet no BFP. I notice my CM never changes. Thick to creamy but never fertile. I really believe I have hostile CM. So I decided to cough up the $$$ and buy some preseed. I'm not trying to be pessimistic but I just don't want to get my hopes up. Has anyone been successful with preseed? Did it not work for you?
