question: Hi. I am subclinically hypothyroid and take thyrox 50 mg every morning. I also have a 2.6 cms fibroid. We are trying to get pregnant. had a follicular study done and on 12th day was given a hcg injection. after this we had timed intercourse. I was told to take 200mg susten once a day for 15 days. I have a 28 day cycle. My periods are delayed just by a day. Is it delayed because of susten? when should i take the preg test. what if the test comes neg.
