Since having my LO I've had very irregular periods ranging from lengths of 33 to 52. They are getting longer it seems :( am currently having initial blood tests. Had my first on tues to see if I had ovulated (test for progesterone) that was CD24 and I had not ovulated, I don't expect to have as my last two cycles have been so long. We conceived number 1 first month of trying so am getting impatient 18 months down the line!! How do people tend to chart their fertility with long cycles? I've started temping this month but have done OPKS but seem to get positives last month at random times! Would love to share stories with people :)
