I'm freaking out. I've been out in the heat. I tried to stay in the shade as much as possible. I didn't have anywhere to sit other than the hard ground. I had to get up and walk around because I kept losing feeling in my feet and toes. I'm starting to cramp from my vagina to my belly button. I'm 5 weeks and 2 or 3 days. Should I be worried?
