Getting self conscious about my baby bump

Hi all, I am 15 weeks pregnant with my first baby who we conceived through <a href="https://glowing.com/glow-fertility-program">IVF</a>. I feel like my bump is too big for 15 weeks and people always seem surprised when I tell them how far along I am. It is making me super self conscious about it. Is it normal or am I just getting fat?
