I'm 37 and about 6 weeks pregnant. I miscarried in aug so I've been going to get my hcg levels checked. I'll be going for an ultrasound wed. When I saw my reg dr last week, she told me no running or strenuous exercising until I see my obgyn. I won't see her until the end of April. So now I'm afraid of working out at all! I live in fear everyday of losing this baby too. I don't want to gain too much weight (I'm starving all the time) yet I'm terrified to exercise.
