Paranoia!😫

Taliyya
I'm 13w4d and still have no sign of a bump whatsoever! I don't have any symptoms besides headaches, hunger and awful heartburn. I have experienced a 2nd trimester missed m/c, so it's just worrisome. I seen my baby on 12/30 and h/b was 163. Everything looked good but next appt is on the 18th and it seems so far away! I'm just hoping all is well with my little bub  #7/14/17 💕
