Positive - Time to celebrate?

Di
I wish Glow stopped asking me to download their <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy app</a> and to share the good news... I don't know if there is anything to celebrate yet!!
I'm in the day 29 of my cycle and I have gotten 3 positive pregnancy tests (pink dye) and a negative digital one. I've been spotting pink for the last three days, and today's test  line is lighter than yesterday's. 
I'm afraid this is going to be my second chemical pregnancy...
