Welcome to PF Moonface , I hear we have a good freind in common PF name Melikins
This is a great forum and I found and still find it soo helpful, and the girls are lovely
Yayy for older mums, I'm near 38 and just had a baby , and it's lovely.
Check out the Trying to concieve section (TTC) and post a hello in there and someone is bound to be able to give you some sugestions.
I would say start making a note of your start and end days of cycle and start looking for any changes in your body throughout the month, as when you start looking, you actually find you can find lots of signs of ovulation time for being more fertile, and also check out pregnology.com using your cycle dates/lengths and it will produce a ticker for you (you cant't have it on here till you have made a small certain number of posts I believe), but is has great infomation on when is your fetile time etc, I used this.
Good luck , hope to follow your TTC and pregnancy journey X JJ
