Whats going on im scared.

Ive been reading too much, but i had implantation spotting and cramps about 3-4 days ago. Ive had two positive tests. One of them being today. But about an hr ago when i went to the bathroom there was light pink when i wiped. And ive been having cramping and nausea like the other day. I dont know whats going on. Any ideas? Im really scared. I was expecting af today or tomorrow.
