To much sex??

So yesterday I was so horny. Me and my husband had sex about 5 times yesterday. Well before we went to bed we had sex again and then after I got this really sharp pain on my right side and it wouldn’t go away so I went to the bathroom and I notice I was spotting this really light pink blood. Is this normal or should I be worried? The bleeding stopped about an hour after and hasn’t returned. Had sex again this morning and no bleeding or pain. A little cramping but not much,
