Pregnant with 3rd baby! Only 5 weeks, extreme bloat normal?

I haven’t had a baby in almost 6 years, so I’m rusty. This was a complete surprise because we weren’t trying. I’m starting completely over from scratch it feels like, and I’m very nervous. I don’t have 1 thing leftover from my last pregnancies/babies so I’m stressed thinking of all we have to buy and do now. I’m only 5 weeks and feel/look so extremely bloated. I don’t remember it being this bad so early. Literally my stomach is huge, and sitting in a car, wearing jeans, etc. is all so uncomfortable already. I can’t tell if this is normal for third pregnancies. Please let me know if any of you had experienced this! Im worried something is wrong, but can’t see doc for a few more weeks. And I don’t have any other symptoms besides sore breasts and fatigue. I think I’m more stressed out this time because it was completely unexpected and 3 sounds a lot harder than 2. Especially since we’ve had a routine for years now. Thanks in advance!
