N.B.
I experienced EXACTLY this..17 years ago or so. I actually got pregnant on the pill..so we were not trying to get pregnant, but it was all fine in that dept. We had been married a while, but were still Apartment living..., house searching at the time, etc.
I had brown spotting, called the doc..(I was young..early 20's..knew nothing), they said come in ASAP. I was also VERY sick. Hyper-emesis. And had been on home IV's about a week or 2. I had an US, no heartbeat, etc. I had a D & C the next day. Testing showed the same as you..Partial Molar. I had to go in every week (not E/O) for the blood tests..for about 3 mos total..till my level went to zero again. I don't remember being told the "don't get preg for X amount of time"...maybe tho?
I was pretty wrecked, even tho it was not a planned pregnancy.
I had 2 other losses and experiences I won't go into here..feel free to message me if you like..but in the end..a year later I was pregnant, had a tough time..but carried it out and have a wonderful, talented daughter who is almost 17 and attends an Arts Highschool and hopes to go to college and major in Illustration!
My thoughts go to you!
