I have posted quite a bit on here recently, just i am getting very anxious as been trying to conceive for 15 months. I had aday 21 blood test to check for ovulation-i hadn't, so the test was repeated on day 28, which confirmed ovulation had taken place. My cycles are irregular. I'm now on cycle day 36 and still no sign of my period. I'm definately not pregnant. Is it at all possible to ovulate and then not have a period ? I'm 39 in 4 months time so i'm getting very worked up now and worried that i will never conceive.
