Anyone gain a lot of weight in first 20 weeks?

I'm almost 19 weeks and I have gained about 25lbs. Feeling very defeated. I don't over eat and I haven't been able to excersize much because I was very nauseous and had awful migraines up up until 16 weeks. Anyone else have this happen? (If you have gained 2lbs congratulations but I really don't need to hear about how little you have gained.. It makes me feel worse. I'd appreciate empathy and would love if someone else had the same thing happen)
