When to start Concieve plus?

Hi everyone

Me and my husband have been TTC baby #1 for 2&1/2 years now and currently at the stage with talking to the doctors and fertility clinic.

After many tests it turns out I haven't actually been ovulating and both the doctors and myself believe it's because I am very overweight. (I am currently on a weightloss journey & have lost 8kg (1stone 3lbs) in the last 7 weeks.)

Along with losing weight I have decided to try the Concieve Plus ovulation support & fertility support.

My question is when is best to start taking these? I am currently on day 5 of my period but they last between 10-14 days. Should I wait until after my period or just start taking them now?
