Crazy story!

Heaven
This is my 3rd pregnancy but no babies yet!
I'm currently 5w2d. For my entire pregnancy I've been having random spotting and even a "period". "Period" was really short and instead of ending like usual, it was a discharge. (Had "periods" with my other two) We thought we lost the baby. I spotted agin yesterday so I went to the ER and asked him what's going on. They did a blood test and a urine test both negative. He did a pap and a cervix check. He did a ultrasound and then he said he saw nothing. I asked him what that meant and he said the ultrasound is fine because I'm only 5weeks. But my cervix shows a healthy pregnancy!
