2 days before period I had brown discharge but only when I wipe. One day late I start to bleed, not heavy but medium I did have clots. I did have cramps. Second day of period I was bleeding normal but that was my last day bleeding no cramps. Day 3 no cramps, no blood. Day 4 I started bleeding again with cramps...WHATS GOING ON??

Thank you
