Spotting?

Okay so i posted about a month ago that i lost my virginity but i made sure the condom wasnt broken at all and didnt have any holes, i asked if i should still worry about being pregnant but women said no. So flash forward to today im starting to be gassy, having a sweet tooth more than usual, really tired like i want to unwillingly go to sleep at like 9 so its weird cause this never happens before my period but im spotting, i had really bad cramps this morning that woke me up and ive been light spotting through the day.. should i worry and get a test or am i just over thinking it?
