Hi, So Me And My Boyfriend Had Sex And The

Hi, so me and my boyfriend had sex and the condom broke. I went to the bathroom and peed and cleaned out my vagina. I got up the next morning and took the morning after pill, but I'm still worried I may be pregnant. It's been 4 days and I haven't gotten my period, but I've had mild cramping and a pinkish discharge. Do you think I'm going to start my period soon, and what should I do?
