Miscarriage at 6 weeks

Today at work I started bleeding and left to go to the ER they said I was in the process of having a miscarriage and my progesterone levels were very low. My bf works graveyard shift from 5pm-5am I work from 6am-2:30pm so I knew he was sleeping but I still called him like 10 times no answer so I ended up texting him well after I left the hospital I came to my moms and I just received a text from him telling me I was lying about being pregnant and a bunch of other things and I’m truly heartbroken that he would even think that low of me. I just don’t know what to do my emotions are all over the place right now.
