hCG level is high in a pregnant patient. What can it be?

Hi doctor,

I am 31 years old. I had two miscarriages around 9 and 8 years ago. My last 6-7 periods were heavy and had a lot of pain. A lot of my family members had fibroids. So, I thought the same in my case too. Two months back, I got my last period, and as usual, it lasts 5-7 days, 28-29 days cycle. Last month I missed my period, felt unwell, had very sore breast that got bigger noticeably. Most of the time I had a nauseous feeling and became moody (mostly sad and irritated), certain smells irritated me a lot, urinated a lot, started eating a lot, felt the need of eating sour things, weird taste in my mouth, my tummy felt full or bloated in a very uncomfortable way and I slept a lot.

One month back, I had 2 pregnancy tests, and both were positive, but the positive pregnancy test was very dark. I used the double pack of ultra blue. After three days, I went to the doctor for a checkup, they withdrew the blood sample to check the hCG levels. I got a call from the hospital asking me to come to see the doctor because my hCG levels are very high. Next day the doctor examined me and then did a transvaginal ultrasound, the doctor told me that the placenta is empty and it is not a normal pregnancy, but it is in the uterus. The doctor told me that no baby would be a result of this pregnancy and he also told me that my only option was the surgery where they remove the cells or tissues like scrapping the uterus. My hCG before the surgery was 28,671. I had the surgery on the same day. The nurse inserted 4 Cytotec pills into my vagina a couple of hours before the surgery. They said it was successful and they removed all of the tissue. They sent the tissue to the laboratory to test it. They said they suspect a molar pregnancy.

What is your opinion? They have not told me if it is a partial or a complete molar. It is 2 days after the surgery, and I am not bleeding a lot just spotting. Today I almost had no bleeding. I thought I am supposed to bleed more, should I be worried? I feel tired; I have this weird taste still. My breasts are less sore, but they are not back to normal. Are those good signs? I read that this condition might develop some sort of cancer. Since my hCG levels were quite high to start with, does that mean I have a higher risk of developing cancer? If there were complications and the levels did not lower down, in this case, how strong is the chemotherapy? Will it have strong side effects like losing hair?
