My belly and butt are always cold :(

AyCr

I’m in 18 weeks now . When I touch my belly (or my butt), it’s always cold... I wear a normal underwear and pants and I also wear socks always. But i don’t exercise at all. At least I do housework like cooking, clearing rooms etc. I don’t why... I’m worried if this is bad for my baby :(

Does anyone have the same symptoms as I do ? Or I wanna have some advices for that .
