I have undiagnosed PCOS and am 23 days late with my period. I only have one working ovary so I have periods every other month. We have been TTC for the last 6 months and have timed my ovulation. I have taken four tests for pregnancy, one being positive but invalid( digital) and the other theee were negative (one with a faint line ). My question is should I retest now that I have let another week go by ? Should I assume I’m not pregannat ? I’ve been bloated, tired and acne for the past twelve days which are all abnormal as well.
