I had dry sex with my bf on sunday. At one point his basketball shorts kept our privates from touching and on another my underwear were in the way. I was already expecting my period that same weekend. I still didn't get it so I took plan b within the 72 hrs. I haven't gotten any of the plan b symptoms. I have been getting slight cramps and the feeling of leaking but nothing. Also my bf didn't cum or pre-ejaculate. I was also getting cramps the day b4 I saw my bf.
