It's very normal because during pregnanc, blood circulation increase, some blood capillaries will dilate.
Usually after a while, when hormones and everything gets back to normal, it will be better.
However, if your skin is more thin or fragile and the blood capillaries is more fragile or what we call the capillaries walls have less elasticity, you might probably have broken capillaries. In this case, you need to take good care, I mean gentle care of your skin. Once the blood capillaries are broken, it's very hard to make this problem to be solved totally. If it's not serious, basic skincare habit need to be caution and not many brands in the market has specific skincare products to treat these kind of skin or problem. At least, those skincare products have more ingredients that focus on soothing, calming or even contains some ingredients (eg. certain Vitamin or Rutin) to strengthen the capillaries walls.
As I know, two brands I know:
1. SOTHYx
2. Bernard Casxxxx
Ribbon,
