Over the moon


So this morning mid morning ish I did a test I'm due on today or tomorrow (I'm not regular nowadays) and to my amazement I got a very faint but there was a line. I cried happy tears I have a neary 5 year old and been trying for a second over 2.5 years. I will do a clearblue digital test in the morning with my first wee but I cant help but find myself so happy although i know i shouldn't be, are false positives

common? I almost feel it cant be real after such a long time waiting. I had a miscarriage before my son and now that's always on my mind. I'm so happy yet mixed emotions.
