Anyone else gaining too much weight even if exercicing regularly?

Vee & her boys👣💙

So guys Im a day shy of 27 Weeks and I gained 25 lbs already. I always weigh myself first thing in the morning and today I am at 142. I was active and eating fairly healthy pre-pregnancy and maintained my habits since Day 1. I still have 13 Weeks to go, my hips are killing me and the pregnancy clothes I bought 2 months ago are starting to feel tight already. I would have thought staying active 5-6 Days a week would slow the weight gain but apparently not... Am I the only one struggling??
