@wadewilson Hey OP, you're not alone feeling that way. Worrying about work, worrying about your own "competency" as a mom, worrying about baby's health all are totally normal and things that lots of working moms go through. I'm at week 37 and went through the exact spiraling sensation when I first found out at around 7 weeks (it was a surprise pregnancy).
One anecdote from my early days of pregnancy - I couldn't get an appointment with my top choice ObGyn, and then felt like I let my baby down / that I wasn't a good mother / that I was too unprepared for what was ahead of me. I broke down crying. My husband and I talked for a long time on WHY I was feeling like this was a big deal. I was worried my baby might have health complications that only my top choice ObGyn would be able to handle. I was worried that a rando ObGyn that I choose might not be a good doctor and miss other complications. Then we talked about what our actions would be if that were to happen. Talking things out with him, I realized that it's not too late to take action once things actually go wrong.
10 months is actually a long time to figure stuff out. You might not feel prepared now - probably are feeling overwhelmed. But take it one at a time, and try to enjoy the process! A happy mom is the best thing for your baby
I also felt like I wouldn't have anything figured out but now that I'm approaching my due date, I am thankful for the long gestational period that God has given us to prepare for delivery haha.
Oh and yes people will be EAGER to share their opinions on pregnancy and parenting. Especially horror stories, if they have them. It's because it's almost like they are trying to process their trauma by sharing it with others. But you're not their therapist! It's ok to tell them to stop sharing or change the subject if it's not helping you feel positive (unless what they are saying is actually a helpful tip). I also personally steered away from reading too many new parent books and whatnot since a lot of them focus on edge cases that aren't too common.
Each pregnancy is like a fingerprint - you'll have your own unique wonderful pregnancy and experience the extraordinary thing that is growing a baby and giving it life
And you'll have the strength and support to get through it.
