I’m pretty sure I miscarried

For a while my fiancé and I were worried I was pregnant. We have tests always ready to take and the day I was going to take one, I began bleeding. It seems to check with all the symptoms of an early miscarriage. I’m only 17 (almost 18) and I’m approaching my senior year in high school. I can’t inform my mom because she’s quite crazy and neglectful. I can’t go to any doctor and this is the second time it’s quite obvious that I probably miscarried. First time being a year ago. I have a lot of health issues, and for a week now I’ve been crying and paranoid that my fiancé and I will never be able to start a family due to them. I don’t want to be pregnant right now, but I feel like I need to talk to a health care professional about this for down the line. I don’t know what exactly to do about it though. Only a few friends and my fiancé are aware that this stuff has happened. I’m just scared and paranoid.
