I started my cycle on the 11th of September and it ended on the 15th. I had sex on the 17th and started the Full body Detox Cleanse on the 22nd. The cleanse is over but I was supposed to get my period on the 6th but it didn't come. I am now 7 days late and still getting negative test. The day that my period was supposed to come, I had dull cramping all night but that was it. Nothing since then. Had anyone ever experienced this or knows someone who has? I'm hoping that I'm pregnant but if not, then it's okay.
