Hi, so I had sex a couple of weeks ago and the condom broke, so the next day I took the plan B, this caused my period to come around 8 days late and I was really worried so took a pregnancy test, it came back negative, once my period came I was no longer worried however my periods are normally around 6 days long and it’s still going and today’s the 9th day, is this normal? Or should i be worried? Could it be linked to pregnancy as its very unusual for me ...
