So l had sex but not intercourse with my bf on january 21 and for precaution l took plan b but three days later. My period came the 26 and it seemed like a normal period. My next cycle was a few days late and it was more like spotting but it lasted like two weeks and l didn’t worry because l thought it was because of the pill but now my third cycle after taking plan b hasn’t come and when it was suppose to come l saw like spotting brownish and pinkish color and lasted two days. And l trying to figure out what is going on??? Is this due to the pill or am l pregnant??
