25 weeks belly bump self conscious

Ok y’all.....I will be 25 weeks tomorrow. This is my second son so naturally you show more than the first time (or so I hear.) I didn’t start showing until 22 weeks and all of a sudden the belly is huge, large and in charge! I lost 120 pounds before getting pregnant with this baby and so far my only weight gain has been 7 pounds and all in my belly all of a sudden. My question is do I really look that huge?? People gasp in shock when I say I’m not due until March and don’t believe there’s only one baby. Am I really that big or am I being self conscious when people say those things? I carry very low apparently during pregnancies which maybe makes me appear bigger? I don’t know I try to not get my feelings hurt but I’ve always had weight issues and when people react that way it hurts a little on the inside. So am I really too big?? Thanks in advance y’all!
