HcG levels drop and rise.

[gsl2908]

I found I was pregnant in August and my HcG levels were at 125 and then 3 days later rised to 215. I then miscarried on a Friday and saw the doctor the following Monday and I was all clear and my HcG levels dropped to 115. The doctor had me wait 2 weeks before testing my blood again. I re-tested again on Sept. 14th. I found out today that last week my levels were at 120. I have to test again this
Wednesday. What does it mean if your levels drop then rise again? My breasts have been really tender and I have been spotting for the past two weeks.

Given that it is not rising very much, I would guess it is retained placental tissue.  It's the placenta that produces the hCG reading, so it can go on for a while if a little bit of living tissue was still attached to the uterus.

As long as the hCG hormone is in your body you'll have pregnancy symptoms. So tender breasts don't actually indicate too much--you'll have it regardless of pregnancy viability or not. As for your levels dropping and rising, it could be due to a vanishing twin or retained tissue. Get an ultrasound from your doctor and have him check your blood work again. If it shows them dropping and/or rising slowly, you'll likely need a D&C done.
