Two different pregnancy apps...

Miri • 7/17/16 8lb13oz and baby boy due 1/2/19!!
Same information into both apps, glow and what to expect when you're expecting. This one is telling me in almost 7 weeks but WTEWYE says I'm 5 weeks and a couple days. I feel like my symptoms really match the 7 week gestation, my husband is convinced I'd be showing by now. I'm tall, thin in weight but wide hips. Dr app is set for next week
