Hi can someone help me please explain when i should ovulate? We have 1 nearly 4 year old and would love to have another one! We have been trying for 2 years and had 2 miscarriages. I wonder am i too old? I am 45. I have tried the digital ovulation tests and now trying the strips but can't make any sense of it?! When do i start testing after period or in cycle? My cycle has gotten more irregular. I have had months where i didnt get a peak according to the digital tests. Is this possible? The doctor prescribed some medicine to avoid miscarriage in d17 in cycle or when ovulate but this or is it last month a much shorter cycle so not sure when to start? I just cant get my head around when my peak/ovulation is?! Can someone advise please? THANK YOU!
