I'm not sure if I should be worried?

before pregnancy I weighed I20  I am 28 weeks and 1 day  and weigh 124 now I went to the dr and they say the baby is looking great and weight great for how far along I am but didn't say anything about me... 
Idk wether to be worried or not I know with my son I weighed 115 before pregnancy and at the end of my pregnancy I weighted 135'
