I think I might still be pregnant...

So on April 8 we get the news that me and my boyfriend are expecting and I'm 4.5 weeks along! We were so happy! Ready to take responsibility for this new little person we had created, well about 4 days later I started having huge cramps and passing blood clots, when I go to the hospital he tells me that everything seems good, and that I'm still showing a positive AGC level, but unfortunately it's going down so I might be going through a miscarriage most likely.
