I took a HPT like two days ago and it came back negative. However my period arrived but 4 days late on the first day of my late period I spotted all day then the next day it was a light flow. Could I still be pregnant?

You have to be two weeks late before you can even begin to expect a test result that's remotely accurate. SO now you wait until you are two weeks late.

So you were 4 days late, but got your period? It's unlikely that you're pregnant.

Late periods happen all the time. Being 4 days late is really not even considered late. The important thing is that you got your period. You will not get a period when you're pregnant. You can experience bleeding during pregnancy, but from what you described, it sounds like you just had an off month, which can happen for many reasons.

Better luck next month. :)
