I’m terrified of losing another baby

My story ... I had my first son almost 3 years ago so once he was sleeping through the night I planned to TTC for baby number 2 I conceived and was due once my son was going to be 2.5 which was perfect but sadly I lost my son at 16+6 so I waited 5 months I think it was to TTC again for baby number 3 my rainbow and I conceived first try I was excited but so scared I had random spotting but everything was fine and I went for my 12 week app at 11 weeks heard the baby’s heart and felt at ease then I had my scan the next day to find out my baby’s heart wasn’t beating 😭 i don’t understand how this happened again I had a d&c the following morning and found out it was another boy.. now I’ve just found out my loss was a partial molar pregnancy so far weekly check on my hcg were 1200, 600, 196 so really hoping it keeps dropping so I can TTC once safe since I have the risk of having a cancer and having to under go a chemo shot/infusion .. I just want another baby 😭😩i just hope I don’t have to wait to much longer to TTC again the plan is from speaking with my doc that I can in November so pray for me 🤞🏼
