Looking for medical insight: declining hCG, conflicting ultrasound information, and paternity concerns

I’m looking for objective medical insight because the timeline and information I’ve been given regarding a claimed pregnancy do not seem to make sense to me. A 26F friend and I had one sexual encounter on June 14, 2026 . We have never been in a relationship. She is now claiming I am the father. When I originally asked about this on August 12, the information I had was: July 20: β-hCG = 156 mIU/mL August 10: β-hCG = 95 mIU/mL The hCG had therefore declined rather than increased over 21 days. There had been no ultrasound or OB appointment that I was aware of confirming the pregnancy, location, viability, or gestational age. Based on June 14 being the only encounter, the pregnancy would have been approximately 10+ weeks gestational age around August 12 if conception resulted from that encounter. I independently scheduled and paid for a NIPP test because I wanted objective confirmation of paternity. Since my original post, several things have happened that have made me even more confused. An OB appointment was scheduled for August 18 . My understanding was that a live ultrasound and another hCG test would be done at that appointment. However, I later learned that she apparently had an ultrasound somewhere else on August 13 and did not tell me about it. At the August 18 appointment, I was told the OB/GYN was apparently relying on the printout from that August 13 ultrasound , rather than performing the ultrasound I thought had been scheduled. The only conclusion I was given from the appointment was essentially that there was still a “50/50 chance” and that the due date was now being given as March 7, 2027 . That due date is confusing to me because it seems very precise given the circumstances and the fact that June 14 was the only sexual encounter between us. It also makes me wonder what information was provided to the OB/GYN when the pregnancy was initially dated. Another concern is that she works at the same OB/GYN office where she scheduled the appointment. I don’t kno
