Check pg test.: Since you haven't been using condoms, and if you are not on birth control, then you could be pregnant and you need to get seen today. You could do a pregnancy test but if it is negative, it is worth getting seen and confirming it with a blood test. If you're unable to get pregnant, then you may be having some spotting, & if that lasts for more than a week, get checked. If you have pain, fever-ER!
