So my husband and I have been trying to conceive for almost 2 years (with a 6month break due to him being in a severe accident). I have an appt to see my gyn next week for a fertility workup, but I wanted to see if anyone else has been through a potential problem I've noticed. I use ovulation tests and take prenatals. We also use preseed when needed. My last 2 cycles I've noticed that we are trying on the most fertile day and then 3-4 days later I start bleeding and have some clottage. I'm thinking it could be that the egg is just not implanting?? Has anyone else had this problem and if so, what was the result?
