Hello! So today I should be 8 weeks and 5 days pregnant. Yesterday my friend and I, who is in her second trimester, went on a long walk to a Fedex and back. We started in the morning and the weather was nice. The highest it got was 71 F I believe. Walking home I had no issues except for sweating. I had some muscle cramping if you want to call it that on my legs, but that's pretty normal for walking long distance. Any ways, it was about 2 hours total walking outside in the highest temperature and I'm terrified I overheated and caused my baby harm. I have no problems and no symptoms of heat exhaustion, but just need some reassurance since my anxiety is high. Doesn't help that my symptoms aren't existent most of the time. Oh, i'm also 19 years old. Fairly young 
Thanks!
