Hello All

My name is Jessica && I'm 19.
I have had 2 miscarriages in my lifetime and just recently found out I am pregnant once again. This pregnancy was unplanned.
My first pregnancy was a blighted ovum, and my second pregnancy the doctor found no heartbeat.
Tomorrow I have an appointment and I am scared to death.
I do have some pregnancy symptoms such as nausea, headaches, exhaustion, bloating, and of course the missed period.
I have no idea how far along I am, not even the slightest clue. My periods have been out-of-wack for the past 2 months.
I was wondering if anyone has gone through the same thing?
I just need alittle hope.
Thank you
