Ovulation tips

Hi,

Currently ttc my 2nd child with irregular cycles. I stopped my pill in December and since then I’ve had three periods (starting 5th Jan, 15th Feb and 29th April) with a 42 day cycle then 73 day cycle. Currently I’m Day 49 and no period. I never experienced irregular cycles ttc my 1st (conceived after a year coming off the pill).

We are going to get some ovulation tests and consider speaking to my GP but was wondering if anyone have advice/tips to start ovulation?

Thank you xx
