Menstrual disturbances can sometimes occur during the early part of treatment with thyroxine
. Normal bleeding is not a feature of pregnancy
. As you had intercourse during mid-cycle, if you happen to have regular ovulatory cycles, you should expect to conceive. This can be confirmed/excluded by a serum beta-hCG
test only as urine tests are of no significance at this stage. You should take the help of a gynecologist as a physical examination may be necessary. Hope your query is clarified. Take care.
