Hello I have been having light cramping for the past two or three days and I'm hoping I'm not pregnant. I went to the bathroom and notice the tissue had bright red blood on it so I wiped two more times and same thing. I am on the orthro patch but last week I was late putting it on but I also had sex the night before I put it on. I supposed to have one more week left on the patch but I'm bleeding and I don't know should I take it off or keep it on could someone please tell me what could be going on?
