Firstly welcome the to the site. I'm Fiona or Fee, mummy to 3 year old Ella and 10 month old twins Abbie and Katie.
When you come off the pill it takes a few months to settle everything down. So you may get extra bleeds or less. Sometimes this takes a few months to settle ( I was told up to about 6)
Personally when trying to conceive Ella we bought the ovulation sticks and thermometer. We spent prob well over £150 on ovulation kits, etc. Never once did any of the sticks, or thermometer show that I was ever ovulating. We tried for almost 15 months to conceive Ella. Eventually Drs started investigating the problem and it happened for us. The only advice I can give when TTC is to stop trying. Enjoy, and dont actually think about trying. We weren't even trying (OK I was still on the pill) and we surpised ourselves by finding out I was pregnant - bigger surprise was it was twins
