I took emergency contraception within 12 hours of condom fail. It was nine days after my period at the time. One week later I had bleeding for three days, not as heavy as my usual period but heavier than spotting, enough for tampons. This was a week before my period was due. A week later, two days befor period due, I had cramping and a light period, that has continued as a light flow for three days now with cramping getting slightly stronger on the third day, but not as intense as usual. Is this due to the large dose of hormones playing around with my cycle? I have taken numerous pregnancy tests from three days prior to due date and one today (due date) and all negative.
