Weight Loss + Pregnancy

Kayla • Wife. MD girl in NC.
I just found out that I was pregnant on Friday (3 days ago) and haven't told my husband yet. He's going to be FREAKING ECSTATIC and although we had started planning for a baby (this came a month sooner than we were supposed to start trying...oops!) I'm not where I would like to be with my weight. I'm a generally healthy person aside from Anxiety and a vitamin D deficiency. Blood work is always normal, blood pressure always perfect. But I am TERRIFIED because I'm so overweight and don't want to have a high risk pregnancy. Any advice on working out? Eating certain things? I haven't had my first prenatal visit yet due to this being so fresh but thought I'd ask 😩 HELP!
