Hi, ignore my username because I'm now going to be a mum of 3! I found out I'm pregnant today so I'll only be about 3 weeks. I was thinking of starting the gym to keep myself healthy with just light exercise, not full on weights and pushing myself etc. Only because when I was pregnant with my second I suffered pgp and bad back pain too so want to keep my muscles etc healthy but is it bad to start exercising when pregnant if it's not my normal routine? I have quite an active lifestyle chasing 2 kids and an active job, thanks!
