Okay, I REALLY need some help here. I had unprotected sex on the 10th of this month. My period was due on the 13th, but it never came. Instead, on the 15th, I noticed brown discharge, & ever since then I have been having brownish sometimes pinkish discharge just about every day. Every now & then there will be some bright red, a very small amount. It's not heavy at all. I feel some cramping & yesterday I was very nauseated & threw up a little bit. I think it would be too soon to take a test, & I have an appointment w/ my doctor on the 22nd, but do you think I could be pregnant or is this my period? I have been having this spotting now for 6 days. I usually spot a little the day before my period, but NEVER more than that. Also, I had to skip my birth control this month. So could my body just be readjusting or something? I'm so confused.
