Definitely look into visiting a Planned Parenthood.
I had a chemical pregnancy which ended up naturally terminating about 15 days after when my period would have started. I had sore and very tender breasts, no real appetite and I just felt swollen all over the place and when I stopped to think about it I realized I had completely forgotten about my period and wouldn't ya know it, I was 10 days late. I took two tests, both super pink and positive, I was shocked. About 4 days later I started having cramps and on the morning of the 5th day of "knowing" I was pregnant I started bleeding. Went to PP they took a pregnancy test and did A. ultrasound and confirmed nothing had implanted and my body was flushing it out naturally. I had very clotted bleeding for a few days and then nothing for almost two months-they said it would take about 6-8 weeks for my cycle to get back to a regular schedule.
Try to investigate a Planned Parenthood near you-their prices are very reasonable and I had a wonderful experience, the woman that took care of me was incredibly kind and sweet.
Also, try to relax, calm down and pamper yourself a bit. This is natures way of saying that your body and the universe weren't quite ready for this baby. You'll be blessed with another when the time is right.
