Pregnant during the winter...should I get a maternity coat

Hello Glow Community.

I am 6w6d pregnant. I will be in my second trimester and part of my third trimester during the winter months and into early spring. I do not want to be super cold in the winter, nor do I want to endanger my baby or get sick so I thought about buying a maternity coat. However, they’re expensive and I wondered if anybody else had tips on alternative ways to stay warm and healthy in the winter months without shelling out big bucks for a maternity coat that I will only use for a few months. Or if anybody has any brand of maternity coat they use and liked that was a good price, I’d appreciate any tips on that front also.

Thanks.
