Weight hasn’t budged

I’ve been feeling really down about my weight lately. I’m currently 9 months postpartum and gained about 27 lbs. during pregnancy. I’m 5’6 and was pretty lean pre-pregnancy, about 118 lbs. I ran about 5 miles a day, 5-6 days a week to maintain my weight and mostly just tried to eat balanced meals when I could.

Well, I’ve been back to running 5+ miles a day for 4 months now and am eating the exact same as before, if not a little less. I’m also pumping 3 times a day. I just stepped on the scale and weigh the exact same as I did 5 months ago - about 7 lbs more than my pre-pregnancy weight. I can still see extra fat around my belly, hips, and thighs and my pants still feel tight.

All of my friends with kids lost all the weight while breastfeeding or right after they weaned without working out at all. I feel so frustrated that I’m back to exercising and eating the same foods as before, but it’s not making even a smidge of a difference.

Has anyone else experienced a plateau like this? Did the weight ever come off without any major lifestyle changes?
