Need help now!!!

Abbigail • Married and expecting a little boy on May 16th, 2016!! 💙😍 we love him so much already!
I've taken two pregnancy tests in that last 4 days. All POSITIVE. and I go to the bathroom today and there is a SLIGHT almost nothing pinkish-ness when I wipe. Me and my fiancé are so excited for this pregnancy and I'm terrified it might have been a chemical pregnancy or something. What should I do? :((
