I just had my 3rd miscarriage and I asked my doc for progesterone supplements. She said to wait ttc for a month and she'd test my levels on cd28. I told the nurse that I ovulate on CD 18-19. From what I read online progesterone is tested 7 days after ovulation. I questioned the date and no one has gotten back to me yet. Is there a reason for testing on cd28? My lp is 11-12 days.
Most REs test between DPO5-7 (7 is most common, but i've had mine tested as early as DPO5) for most accurate view of whether ovulation has occurred. How long is your cycle normally? CD28 seems late to me...but my cycles are shorter so for me CD28 i might already be into next cycle
That is not very accurate of your doctor. Progesterone should be tested at 7 DPO (ideally) sometimes a day or two earlier or later is fine, but 7 dpo is preferred.
My doctor wanted me to come in on CD 21 even though I told her I ovulate late. Did I listen, no! I went in at 6-7 dpo (still unsure). There is no point in me going in on CD 21 when I haven't yet ovulated and wasting $50 for a copay!
My 7 dpo test came back as fine, but the problem with that as well is that I think my progesterone drops off suddenly (pregnant or not) around 11-12 dpo. She hasn't tested me then so she doesn't know for sure (and neither do I) but I think that is what happens with me. I am on progesterone this cycle for the first time so we will see if I get pregnant again if it helps the little one stick.
All I have to say (and this could be the progesterone speaking ) is that sometimes doctors are absolute idiots and don't really think about what they are telling us. Not only that but each of us is so different from the next person and a lot of doctors don't give individualized care or instructions.
My RE puts all women she sees on progesterone suppositories post ovulation, high doses of folate and low dose baby aspirin. She said that this combination seems to help the most women, but even that doesn't always help.
I would say try progesterone - it can't hurt and can only help if that is an issue. If you do end up on them, stay away from oral pills and go for the vaginal suppositories. They have the least side effects from what I have experienced and read.
I agree with the other girls... that is too late. Your levels could be dipping again by then if AF is coming. I'd ask WHY she wants to test you that day. If she wants to see if you are ovulating 7dpo is the correct day. If she wants to test you on CD28 after a pregnancy test, that is a different thing. (even though you may not get a pos by that day if you do get pg). I'd ask WHY she wants to do it that day. If she doesn't give you a good answer. I'd find another Dr.
I currently have a friend whose Dr. wanted her to test on CD21 even though she happened to O late and so was only 2dpo when she tested, they told her she didn't ovulate, even though she felt it and her temp spiked. Sometimes Dr.s lump you into the "Average" category when that isn't the case.
I'd not waste your money or ins on tests that aren't going to give you real answers.
I do agree that progesterone and baby aspirin are a good thing to try when ttc after a m/c.
I'm so sorry for your loss....

from what i was told she's checking my progesterone levels on a non pregnant cycle to see if I need supplements for ttc. Why cd28 i cant figure out. I know I'm ovulating by temping and opks but i think a little too late
