I took a pregnancy test yesterday. It showed a faint positive, meaning the second line was not that dark, however it was there. My friend, who has been pregnant twice says that this same thing happened to her and each time she was pregnant. Yesterday I was about eleven days late for my period. I have experienced all of the symptoms, including breast soreness, nausea, exhaustion, and strange feelings in my stomach. My stomach has constantly felt as if I had thrown up several times in a row, that soreness that you feel afterwards.
Today, I did not feel my period was starting or anything like that, I just went to use the bathroom. When I wiped, there was blood on the toilet paper. There was no blood in the toilet or on my underwear. I've been having cramps today, and every time I use the bathroom when I wipe there is blood, but nothing on the pad, and nothing in the toilet when I urinate. To add a little more complication, my mother never skipped her period during her pregnancy with myself and my twin brother.
Is that hereditary? Is there any way to tell the difference between spotting or possibly miscarriage?
I am so confused right now, after having a positive test result, and then seeming to start my period. I know that no one here can tell me if I am pregnant or not, but has anyone experienced something similar? How heavy is too heavy for spotting?
As I said before, I was about eleven days late, I did not have my period at all in nov. Could I just have skipped the month? My periods tend to be very regular.
Any help you could offer would be great. I can not find out more from my mother about her experience with period and pregnancy because she is very religious, and would be upset if I asked her about pregnancy. My fiancee and I are very much in love and planning to get married next year, we were not expecting this, and we are both very confused with the mixed signals. Any kind of help would be great.
Also i've been experiencing headaches and severe dizziness for the past week and a half.

Thank you.
