Surprise Pregnancy

I’m 7m PP, had a little girl in October 2020 and just found out today that I’m pregnant again. My pre pregnancy weight in February 2020 was 244 and after having my daughter I got Nexplanon and gained almost all my pregnancy weight back in two months and have been having the hardest five months trying to loose it. Then “surprise” this morning I got a positive pregnancy test five days before my period is supposed to start. I’m currently 270lbs and am working out all the time, this of course out a bump in my plans but I’m wondering if because I’m plus sized if it’s okay to continue to work out moderately while pregnant, I’ve lost almost 25lbs after initially loosing 30+ after having baby and then the fiasco with my BC implant and I want to continue going, I don’t want to go over 300lbs and I don’t like being over 200, I was trying to loose weight when I got pregnant last year and stopped and it was the worst decision I made

TIA
