Confused?

October 17th I had sex WITH a condom. it ripped and we stopped immediately. Just in case I took a morning after pill on the 19th. Two weeks later I hadn't gotten my period so I took a test and it said negative. The day after I took the test, I got my period. It was a regular period with all the cramps and the PMS and it lasted as long as usual. Now it's month two and I havent gotten my period. I haven't had sex since I took the morning after. is anything wrong? I've been mildly cramping but that's all.
