My legs are cramping like when I get my period. And this morning I saw a little bit of brown gel looking stuff when I wiped. And now there like a dark line of blood in my undies. But not enough to go through. I got my period like the 14 of April and it ended the 18. I had taken plan b on the 22. My cycle is normally 28 days. Is this my period? I have taken plan b before and I got it 3 days late
