Miscarriage

So I've had spotting for about a week and everything seemed to be going well until last night. I had small cramps but nothing crazy. All of a sudden I had these horrible blood clots the size of a golf ball come through with more heavy cramps but it only lasted for about an hour. I didn't fill up a pad as it was only blood clots coming through. I'm making myself crazy by looking online with my symptoms. Some people say miscarriage and some people say hematoma. I have to wait for 3 more hours until I can call my doctors office to see if they can check what's wrong. I didn't go to the ER because I really didn't want to have to pay thousands of dollars for them to tell me the same thing my OB will tell me for less than 30. I don't know what to do. All I've done is cry and pray that everything is ok but I still have this gut feeling that it's gone. This was my first pregnancy and my first miscarriage. I really want to try again but I'm having a hard time thinking about it right now. Sorry for the rant.
