Regretting trying so soon

I hope this isn't offensive to anyone. We lost our son in June of this year to trisomy 18. I will be completely transparent - we did end up having a missed miscarriage 2 days before our appointment with the clinic for TFMR however this group and the TFMR support group are the only groups that I can relate to.

We immediately started trying again. With our first cycle with ovulation we didn't get pregnant and I was initially very relieved...we went back and forth about whether we were going to try the next cycle and I (husband was very supportive either way although I know he was definitely ready to try again) ultimately decided let's try - thinking maybe I'm not 100% ready but that I didn't want to put it off.

Now we are pregnant (about 6.5 weeks) and I really worry that I'm not ready for this. I know I'll love this baby but can't help but be angry and anxious all the time. It doesn't help that this pregnancy came at a bad time with me accepting a new job with a start date at the 20 week mark (I have no idea how to navigate that since we found out we were pregnant after I interviewed)

Anyway, I mostly wanted to know if anyone else had initial regrets about subsequent pregnancies and how they were able to process and move past those since I am struggling.
