Yup, still pregnant!

Megan • Happily married. One 2015 angel baby, little girl born Sept 2016, & one due June 2019.
I read too much and panicked. A few of my symptoms went away and I just didn't feel pregnant. Took a test this afternoon. The line came back dark almost immediately as well before the control like. Ugh, so thankful. I know I'm not the only one who has freaked out like this. My doc appt isn't intil 9 weeks. When will it be "safe" to celebrate and stop worrying so much!?!?
