Struggling to gain weight :(

Anyone struggle gaining Weight? Or their midwives/ob wanted them to gain more Weight? I've been vegetarian for the last two n a half years. So it was no problem for me maintaining my diet throughout my entire pregnancy...so far I've gained about 25 lbs. Coming from the 105 I was at before. Putting me at 130 now, but I've stayed here for the past few weeks. I have a birth profile ultrasound today to check in depth and make sure babe is growing accurately and on time but wondering if anyone was vegetarian, or had low weight gain? How were your babies and if you had any other issues?
