Short of breath!!

Patricia • I am 40 years old and just found out that I am expecting! It was definitely a shock! This will be my 2nd, 1st for my SO!
So, I am only 7weeks and i just ran a few errands and it like completely wore me out! I got so short of breath I had to stop and rest! I am not going to make it, once my bump gets bigger! Geez! I am hoping it is just the Atlanta heat! It's 86 and very humid! Anyone else feel like this so early?? I hope it doesn't get worse
