Help!

I took a pregnancy test yesterday and it was the little strip and there was a faint line so I went out and got a first response and it also had a light line. Last night my husband and I had intercourse and there was a little bit of light blood and I'm freaking out. I would be almost 5 weeks, my last period was April 12th. Am I losing the baby?! Is this normal?? I'm so scared
