Back to back miscarriages and struggling

Cass • Baby girl- 2yo Angel babies x 2

I don’t know what to do I feel lost. MC at 12 weeks in June and now a chemical this past week....my partner is great about it but they just don’t understand what we’re going through and seeing as he has a son from a previous relationship he doesn’t have that desperate desire to be a parent like I do.... have an apt with OB-GYN next week but I’m just feeling a little lost today.
