Exercise while pregnant

Al

Hey ladies!! I’m almost 5 weeks and prior to finding out I was pregnant last week I was staying under 1200 calories from Jan 1 and lost 17 lbs in those 11 weeks... I’m still not at my ideal weight but now that I have a growing bean I feel like my plan of 1200 isn’t going to work anymore to give baby what it needs. I read online to add an additional 150-300 calories. So if I do 1500 calories maybe I will still continue to lose. I know this is a question for a doctor and I plan to talk to mine soon. Just wondering if anyone has been through this themselves. Is it safe to lose weight still while pregnant? And I am not the type of person to get ANY exercise. Is it too late now that I’m pregnant to just go for long brisk walks with my dogs?? I stated in Jan at 173lbs 5’2 and now I’m 155. Thanks for any advice!!
