I just wanted to chime in here. I have had a few issues, one being that I wasn't ovulating on my own. Clomid got me ovulating but I was spotting before my period and I felt my temp was falling too soon. I finally insisted on getting my progesterone levels checked on my 3rd Clomid cycle and they were low. Got them checked on the 4th clomid cycle and they were low again. I had to take a break from the clomid and ovulated on my own the next time, low again. On my 4th clomid cycle and my first natural cycle I had gotten pink lines on IC tests (they were a little odd but definitely a line and definitely pink, not an evap). I should add that my spotting didn't start when it usually did for those 2 cycles with suspected chemical pregnancies.
On my 4th clomid cycle I got 1 positive test, then negatives after that and got the progesterone prescription and started it the night after that first positive test. I had started spotting by then. I kept spotting while I took them and my BBT temp rebounded but I didn't get positive tests and a blood test 4 days later was negative.
On my first natural cycle I got 1 questionably positive test (line appeared after the time limit... DH saw it on the counter an hour after I took it). So I took another test that evening and got something. I got 2-3 more lines on subsequent tests but started spotting and didn't bother with the progesterone (temp had already started to drop).
On this cycle I ovulated late but am seeing a different doctor. He had me come in for the blood test at 5dpo then when that result came back low, he put me right on the progesterone. I'm really hoping its all I need to get my BFP. Otherwise its going to get a little expensive.
Here were my progesterone blood test results (US figures: a 10 is the minimum they want to see for a natural cycle, 15 for a medically stimulated cycle, anything above 3 is considered ovulatory). Blood should be checked at 7dpo.
Clomid round 3: 6.5 (taken at 5dpo)
Clomid round 4: 8.8 (taken at 8dpo)
Natural round 1: 6.9 (taken at 7dpo)
Natural round 2: 4.2 (taken at 5dpo)
I'm taking the 200mg vaginal suppository once at night. The form the progesterone is administered in does make a huge difference. Some forms have minimal impact on the blood progesterone level or no effect on the BBT. As you can see on this cycle and 2 cycles ago, when I take the progesterone suppository, my temp definitely goes up.
leesa - I have to say your story has helped me keep my hope up for this cycle! I'm really hoping it works just as simply/easily for me as it did for you!
