Should I be worried about low progesterone? I am 4/5dpo. I know my temperature is high at the moment but it has slowly been getting lower. This is my second cycle post miscarriage. Last cycle my post ovulation temperatures were really low and from 6dpo they dropped below cover line and I got my period early (I actually think I had a second miscarriage as I got a positive test but then period came). Im worried this is going to happen again! Any advice?
