spotting great amounts...

Hi,
Welcome to ehealthforum,
If your periods are regular, then the timing of your unprotected intercourse could be during your fertile days/probable ovulation time. You are closer to your ovulation time after finishing with periods. The pink/fresh blood spotting that you describe could be the probable implantation bleeding. Wait and watch for your next periods. If pregnancy is suspected, look out for development of any other new symptoms suggestive of pregnancy. If periods do not start within 10 days of expected period dates, or if you get abnormal periods, or if you suspect chances of pregnancy, consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately).
If pregnancy gets ruled out, and if you are not ready for pregnancy, but intend to remain sexually active, you should consider visiting your gynecologist to get started on suitable regular birth control measures to be protected (after your periods) as well as regulate your periods. Be regular with birth control use as instructed. Avoid having unprotected sexual contact. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet.
Take care.

The blood came out fresh at first, now I am getting blood which appears maroon and brown..I'm guessing old blood. I am not supposed to get my period until the 6th of January....should I wait it out or is there any other way of finding out sooner through tests?
