I'm 18 and have had a normal period since I was 13. I became sexually active about 6 months ago and we've always used protection. The only time we haven't was about a month and a half ago. I had a period last month that was a lot different than usual. No blood on any pads except once and it was just a little bit. Only blood when wiping and It didn't seem to last even 4 days. This month is been the same. Only blood when wiping. Very light cramps for about 4 days before I even saw any blood. I've also had pretty bad cramps since I started noticing blood this morning. I'm not sure if this could be that I'm pregnant or just under stress.
