I am 34 and have 2 girls aged 2 and 3. My eh and I have been trying conceive for 5 months. We fell pregnant very easily with our first 2 but not this time. My cycle has changed in the last 6 month. Very long cycles, (normally 32) days but now more like 45. I am not even sure if/when I am ovulating. Usually I can tell with CM changes, I have never charted anything before because that was very reliable. Now, I do not have the same egg white CM that I usually get during ovulation - slight changes, but not like usual. The first day of my last period was 1/6/12 and I am still not sure if I have ovulated yet.

Has anyone else had changes like this in their cycle and conceived? I am worried the might be something wrong.
