22 week weight gain


So I’m 22 weeks and I’ve gained 20 lbs already. My doctor said it’s more than they would have liked at this point but since everything is good with baby and me and I still exercise 5 days a week just to be careful with what I eat. I haven’t really changed my eating habits but the terrible morning sickness I had stopped a few weeks ago. With my 1st I gained 60 lbs and lost it all by 4 months postpartum. I have cut down my cardio just because I had hip surgery a few months before I conceived and the pressure is bringing some unwanted recovery results. My husband is over 6 feet tall and our baby measures is the 87th percentile if that makes any difference. Any advice?
