Light pink spotting

Is it normal to spot after sex. The last 2 times I've had sex, I've had some very light pink spotting but I'm just confused as to why now. My husband and I have been intimate for almost 4 years now and it just happened the last 2 times we had sex. Before you ask, I was very much "lubricated" lol I have also experienced a bit of cramping and feeling bloated shortly after sex.
