Constant doubt, Daily Home Testing

I'm freaking myself out. I can't wrap my head around the fact that IM REALLY PREGNANT. OMG. First time Mom, first known pregnancy and I'm going nuts. I'm so anxious, I'm testing every morning. (Down graded from the name brands to dollar store tests after the first five)! I'm just so scared I'm gonna miscarry. 4w4d along and I can't keep living like this for the next month till my prenatal!!!! How are you ladies dealing with the anxiety? (If you're anxious!!) or are there any other Mamas testing everyday like me!? Tell me i'm not the only crazy one!
