hi i'm 36, 220 lbs and 5'4" tall. I am having light brown discharge for the past 5 days. I did not ovulate on time this month (have ovulated ontime for the past 3+ years that i know of). The discharge started on cycle day 15 and i usually ovulate on cycle day 13. IT started heavy for two days and light after. I have normal periods that come every 27 to 29 days and last for 4-5 days. The past two months i've had 5 days of spotting after my periods. I used clomid three months ago for a test for my fertility specialist. The specialist says my hormones are find and my uterus shows no reasons to be spotting. He says he will test my TSH levels.
