Hi, I took levonelle 5 days after my period and then had heavy period type bleeding about 3 days after which lasted for about 5-6 days. My period excluding the mid-cycle bleed) was due last Tuesday and is now 7 days late. I have taken 3 pregnancy tests and all are negative. Has levonelle changed my cycle or could I be pregnant? I am now getting spotting and pre-period type pains but no period!
