Barely Gaining Weight

Cierra

So some background info. Im 22, ftm. Im currently 26w3d so im about to enter the third trimester. From the backside i do not look pregnant. Ive been thick my whole life until last year, i weighed 134. First trimester i was 136. Second, 142. My doctor has no concern for my weight gain or loss so i shouldn't be concerned about it. However, Glow keeps reminding me i shouldve gained at least 25lbs by now.

Anyone else gain very little and things have been fine?
