My cycle is usually 24 days long. My last period started on Monday 26th September. I was intimate on 9th October in the afternoon. For the first round we used withdrawal but there was precm, and I'm sure he did not ejaculate inside me. After this we used a condom. This was the 14th day of my cycle.
I had my usual pms, nothing out of the ordinary. I was expecting my period on 20th October but it has come on 22nd October in the evening. It's bright red blood but little in amount. i also have cramping.
Also, during my last period, I was on antibiotics for a week for tonsillitis.
Is this my period? Should I be worried?
