Weight gain

G
Sorry if the pic is hard to read. The beginning of the year I was trying to lose weight(and was struggling!) then I got my BFP on March 13th, so I've been tracking my weight still. I've gained a total of 13 pounds this year, and since the ending of my last period I've gained 10.4 pounds...not sure exactly when I got pregnant so I'm going off the last day of my period for weight gain. So is 10.4 pounds to much for 15 weeks pregnant? My doc told me to gain 11-20, which I'm pretty sure I'm gonna gain more then that. Just wondering if I should be concerned.
