Help!

Hey all!

I have been ttc for 4 years with one miscarriage this month I started taking macca and coq-10, my cycles are a little confusing some months I could be every 4 weeks other months it could be 6 weeks. My last period was on the 23rd feb(1st day). Today I was getting really dull aches so randomly done an ovulation test. Not sure if it’s positive. Any advice would be appreciated as we are currently going through nhs for help as they don’t think I’m ovulating thanks xx
