Confused.

Destiny
So, I missed my period this month. It was due 12 days ago, but it never showed. All the tests have been negative as well. Yesterday during work I started spotting lightly, it continued throughout today but has stopped now. I thought it was af but it can't be if it has stopped so soon, as I have very regular flows, always between 5-7 days. I just wanted to know if anyone has had this happen and ended up pregnant, and whether they got the answer from an hpt or had to get blood work done. Feel free to share stories and opinions ladies, thank you.
