Pregnant?

Selena

Okay so me and my fiancé have been trying to have a child I have a two year old already, but my period is now 5 days late I also had light spotting 1 week before my period the next day I was cramping in my lower stomach and the next day I spotted again and I’ve only been nauseous and headaches and eating more and he’s been the same as I have I dunno if I’m pregnant but when should I test?
