Miscarriage and live birth trend

I’m curious if anyone has had a trend of live births and miscarriages. I recently had a miscarriage at 9 weeks when everything f was going perfect. I even heard my baby’s heartbeat at home on my Doppler and then miscarried that same night. I have a 2.5 year old son whom was my first pregnancy, no complications and very healthy. After him I had an early miscarriage at 5 weeks. Then immediately got pregnant with twins right after. Unfortunately that pregnancy ended at 26weeks due to TFMR because they both had an incredibly rare syndrome. Prior to that diagnosis, I got pregnant easily and had a pretty good pregnancy otherwise. Since I did not carry to term my MFM said to at least wait 2 maybe 3 cycles before trying again. 4 months later we got pregnant again which resulted in this recent miscarriage. I know miscarriages can be pretty random, but not sure if related to chromosome abnormalities or something specifically with me. Would love to hear success stories for encouragement. Also my husband and I got tested for what our twins had and are not carriers for that. We do plan on doing other genetic testing just in case and may consider IUI or IVF if needed. I’ve always wanted my children to be closer in age and it seems like we just keep getting set back:(
