2 miscarriages and now progesterone

Long story short...I have 2 healthy kiddos no issues. Tried for a 3rd, and I've had 2 miscarriages last year. Finally healed enough and we are trying again. On month 3 of trying after finding a new OB, doing all new bloodwork and discovering more answers. MTHFR gene mutation and low progesterone and another little thing I can't remember the name for. PIA? PAI? something or another.

Anyways. So it's the first month of taking progesterone 200mg and I'm going crazy. 2 different trackers had me ovulating different days, so I'm anywhere between 7-9 dpo right now. I'm aware the extra progesterone is giving me all the symptoms and struggling to have hope that it'll actually happen this month. My bday is Thursday and I may test then, fingers crossed, but I don't know if I want to be disappointed either. Ugh. Talk me off the ledge! I've been nauseated all morning and constipated and gassy and so flipping exhausted and emotional and all the things that I know by fact are because of the added hormones and not because of anything else yet. Who else has taken progesterone? Thoughts? How many months did it take for your bfp? Give me hope, ladies!
