so I found out I was pregnant last week. and my lines are getting darker. this is my third baby

inhad a rough time trying to conceive no 2. we suffered a miscarriage and then conceived no 2. so I've always been alittle anxious but my last period started Dec 26th. my first dr appointment is Feb 17th. is that to soon to hear anything? also i have lower back aches on and off all day. is this normal? this is my test today
