I have had success with clomid in the past, but due to an abusive marriage (which I am thankfully out of) I miscarried every time. I am now on another round of clomid with my current partner, but am confused as to when I am actually supposed to start. If clomid makes you ovulate, wouldn't your cycle be 28 days, or something close. Since getting off the nuvaring in May, I have had very irregular periods. Most of them were 37 day cycles, but the past two months have been longer and longer. This past month, before starting clomid my cycle was 49. I also have PCOS. I am just trying to figure out when to take a pregnancy test. I don't wan to test too soon, as I have enough disappointments with all of this.
