5weeks: weight gain, occipital neuralgia, and boobs!

Crystal

I'm 5 weeks 3 days today, and I've gain 12lbs in the last two weeks! I've been exercising everyday for an hour, and im just so amazed how much weight I've gained! Ive never weighed this much my whole life😄 my primary care doctor said it's probably the progesterone and water weight? I had to see my primary care today because i take nortriptyline for occipital neuralgia, and ive been on it for 2 years. They say they are unsure of this treatment in pregnancy, so maybe i should get nerve block?😬 im worried. Dont know what is safer. Anyone else have occipital neuralgia and pregnant? Also, has anyone else boobs grown already? Im already a cup size bigger. Went from a C to a D. I hope im doing ok. Is all this normal? Maybe I need to do cardio? If the weight gain is too rapid... Maybe it's the extra milk I've been drinking?
