Totally miserable today! My tummy is upset and now I am having lower back pain 😓 I am only 26 weeks as of yesterday I am hoping this is just a tummy bug 😖

Am I seeing things....

Already have gone through 5 scans because of changing gynec

I am a thicker girl, I am 5"9 1/2 and the last time I went to the doctor I weighed 239 pounds . I have always had a little tummy , but when will I start showing ? I am currently 17 weeks today , and I honestly can't tell if I'm just fat or ... I'm starting to get a baby bump. ( I'll insert a picture of my pre baby body.)
Hey! My name is Liza. If I am pregnant, I will be a single mommy. I still am waiting for an ultrasound, though. I'm from Denham Springs, LA. #myfirstpost
