I had unprotected sex about 2 weeks ago, 3days after my previous period ended, I ve been feeling so tired and not wanting to get out of bed since. My breasts are very sensative I ve been urinating regularly, craving sugar foods , suffering slight headaches and when I go to the toilet and wipe I have been getting light bleeding and brown discharge . I m also getting slight cramps in my right side just below my belly, nothing agonising just uncomfortable as if I ve pulled a muscle this has been happening for 3 days, I m not sure if I m pregnant or I m just expiriencing a 2week early peruod which has never happened before
