I need help... I had unprotected sex wit my boyfriend on June 4, 2011 and again on June 7, 2011 and again on June 12, 2011. I started spotting June 17, 2011. My period doesn't come until like June 24 or later. A week before spotting my nipples wore sore and I was having headaches. The morning of the spotting I woke up really sore like I had been lifting weights or something.I took a test but it said negative. Could I be pregnant?

even if you were pregnant a pregancy test would not give you a result yet, because the pregnancy hormone that is detected in the HPT's will not be present at this moment, you need to wait until or if you miss your period using first morning urine. You could very well be pregnant, sex=babies.

I would say yes there is a good chance, you seem to be wanting to become pregnant, since you are having continued unprotected sex. So good luck
