ovulation testing after M/C?

hey ladies, how do you know when to start testing again for ovulation after a miscarriage? I lost another baby last week and my bleeding is just starting to slow down. I had already past everything by the time I got an early scan at EPU on Thursday. Im being referred to look into recurrwnt miscarraige now but I will obs have a waiting time with the NHS and we want to try straight away again. When did you start using OPKs? My miscarrige last year took about 3 week for the bleeding to stop ans another 3 weeks for my AF to return but I wasnt as far along this time so Im thinking it may return quicker than last? 🤔 Any advice appeciated x
