I feel like I have a problem 😢

Brittanie • Mommy of a beautiful 4yr old girl and I am pregnant with another baby girl due February 2018 💕 couldn't be happier! 👶🏼
I am ttc #2 and just started my period. This is  cycle #3. I am going on cycle #4 and it took nothing to get pregnant with my daughter. She is 3 now and I just feel like there is something wrong with me 😢😢😢😢😢 I need opinions. Should I make an appointment with my obgyn?
