Been TTC for nearly a year and been taking folic acid since jan this year. Have used ovulation tests before, haven’t for the last few months because I never got round to ordering them but have been having peaks previously. For the last 5 months periods have been becoming more irregular with this current period being about 16/17 days late but still have negative tests. Waiting to gp appointment but they are like good dust at my doctors surgery! Looking for any advice possible!
