Is progesterone delaying my period?
I'm 41 years old. Last year I miscarried at 7 weeks. I suspected low progesterone, but the doctors did nothing about it. I also have very small fibroids in the uterus - less than 2 cm. I have not fallen pregnant since, but have felt that I have conceived over 5 times in that period as my pregnancy symptoms are very pronounced (immediate breast growth up to 1 inch, nipple swelling, breast pain, horrible acne!)
The last time, I started the progesterone (20mg morning and night) - I felt bloated and pregnant, so I cut back to 1/4 morning and night, then got my period on day 15 after ovulation (I am always spot on - ovulation between 12-15, then 15 days after I get my period). Well, that period was exactly like my previous miscarriage with little hairlike fibers in the bleeding.
So this month, I decided to do the full dose the entire time, and now I have not gotten my period - 5 days late, but with no pregnancy symptoms and negative pregnancy tests. I quit the progesterone 2 days before my period was due after a negative pregnancy test.
My question - what dosage should I be taking? Am I taking too much? When do I quit taking the progesterone if I am trying to conceive? How will I know for positive that I am not pregnant before quitting the progesterone? What is the best route to use when using progesterone when trying to conceive?
Thank you very much.
