I started my period on June 24th and it lasted 7 days. Ended on June 30th. I used an ovulation calculator and it said that I ovulated right after my period. So with that being said I had unprotected sex 2 days after my period ended. July 2-3. Soon after my breasts hurt so bad. Nipples super sensitive and sore. Now its been 12 days after my last period (july 15th) and I'm bleeding again. Its bright red on the tissue but I have to wear a tamp and its like a period. Does anyone have any answers for this?

It is possible to be pregnant as you can still "spot" or bleed during pregnancy. However you could just be having an irregular period. It is fairly common, but sometimes it can lead to a bigger issue. I recommend going to a planned parenthood and seeing if there is a worse issue. They can often provide for financial help however if you still feel like you can't afford that, wait until 4 days prior to your next big period and take a pregnancy test. As for a miscarriage, that is usually followed by extreme cramping and discomfort, but 1 out of 3 women will experience a miscarriage and not ever even know it. If you experience pain and continued bleeding I would definitely consult a doctor. Otherwise just wait to take the pregnancy test.
