Is light spotting after sex normal??

Im about 3 days late for my period. I’m praying I’m pregnant. I’m having most of the symptoms which I normally don’t have with PMS. I had very little spotting after sex this morning and i pray it’s not my period coming. Does anyone know if it’s normal to have light spotting after sex in the early weeks of pregnancy? Also, i have noticed that the last few weeks have been way more difficult to orgasm when usually its very easy. Does anyone know if this is also normal in early pregnancy?
