TM - My normal cycle was exactly 4 weeks in length. I would get AF on Sunday, 2 weeks later get a positive opk on saturday arvo or night.....then AF again 2 weeks later on Sunday. When taking Clomid I think I O'ed slightly earlier as I woke up saturday morning with a +. My Dr said to start testing at 10dpo....but that depends on how short your cycles are. If it makes you more comfortable just start after the last tablet. Use the SMEP....attempting every second day from cycle day 8 until positive opk...then 3 attempts...miss a day and attempt again...then in 2WW. Hope that makes sense.
Clomid works by blocking estrogen receptors at the hypothalamus, which is an important "hormonal control center" for the body. When this happens, the hypothalamus is stimulated to release follicle stimulating hormone (FSH), and luteinizing hormone (LH). These are the naturally occurring ovarian stimulants, which prompt ovulation in a normal cycle.
I felt fine when taking it...got hot flushes and felt a bit weird in the head but I took mine before bed which reduces the symptoms.
