Full molar pregnancy & My17-year-old daughter

My daughter found out she was pregnant December 1st 2024. Everything was normal and so we went for the first ultrasound where we found out she was having a full molar pregnancy. Apparently that's where it's not a normal pregnancy but a growth of uterine tissue. It acts as though it's a normal pregnancy in the ways of how the hormones progress and your uterus grows and even regular pregnancy symptoms! She had to have the tissue remove and then they dmc. We had her blood work done right after the procedure and all the pregnancy hormones were going down by they were supposed to. Now fast forward a few weeks later for hormones have doubled from $400 to 900. I know that this could be a sign of a worse Medical situation that could even cause cancer but here's the catch... even though she's been "Medically" & "Momma" advised not to have sex at all she still has continued to be sexually active unprotected! Yes, I know I could have killed her! I'm honestly just glad that she feels she can come to me even though it's a very personal matter and something that most girls would not go to their mother about. My biggest question is what is the possibility medically that this is not the molar pregnancy growing tissue again but that she might be pregnant again? I'm trying not to get my nerves up for either outcome but I know everyone on here is very well educated and all these matters! Thank you in advance!
