Yes, please go do it!Your family and friends, like mine, may make you feel like you need to stay on your couch and sit perfectly still for the next 4 months. Hogwash.Women run marathons pregnant, up until the final weeks of their full-term pregnancies... NOW- those women were running marathons before they were pregnant, so their body was already in respective shape for that.I'm a distance runner, and I ran until I just didn't feel comfortable anymore- 34 weeks. I also did judo up until 20 weeks. I'm 39 weeks and now I'm walking at a steep incline on the treadmill [usually NOT an option for me, but it's kicking my butt!] and I still use thei weight machines at the gym. At home, I use 5 lb. dumbells. It all depends on your fitness level and what you did before. Talk to your doctor to be safe.Since you say you've been out for a while, you'll notice little changes that may discourage you at first- this is only the beginning! It may be a little harder to breathe, for one.People will think that even walking will make your baby fall out of you, or if you're cleared to run, that he'll end up with bruises all over him, etc. Then, tell me, what's the amniotic fluid for!?!!? You're baby is fully surrounded my that fluid, and right now, probably the size of a shrimp. Yes, you need to be careful, but that baby has a lot more protection than we think.Just remember to eat extra calories if you'll be burning them and to drink water like you've never drank it before!!! Working out is fine, probably encouraged by your doc once he brings it up, but don't try to lose weight!
