In October and November I missed my periods and when I went to see my doc the blood test showed that I have very, very high estrogen level in the blood (almost 1000). Also, the pelvis Ultrasound showed that I have lots of big (5-6 cm) cysts with walls on both ovaries. My ovaries were clean back in July when I did the CT scan.

I was put on 2 nine month durations of Provera to induce ‘pseudo-pregnancies’.

I had a transvaginal ultrasound and it showed that my left cyst and increased from 2cm to 4.5 cm, but described as “simple”. After 2 miscarriages it was determined that I had an ‘inadequate luteal phase’. Ten years ago I started having very heavy periods, very frequently (10 days long every 21 days). I asked him about an endometrial ablation and he referred me to another specialist. I still had minor spotting at the time of my periods… My oncologist ordered a blood test and it showed my estradiol levels as high (386). In 1977 I got pregnant and was one of the first users of progesterone suppositories. I should mention that I had genetic testing and I came up negative for the BRCA1 and 2 genes.
