Little spotting yet no period

TIFFANIIE • 30 single mother of a handsome 12 year old son Im not dating but i would love to have another child by 35. Natural or adoption is OK with me.
My period was suppose to come on 4 days ago per glow so i put it was late. Waited today for it to arrive yet I put a tampon in today cause I felt minor pain in abdoman but it was very light and no more pain. Should I test for pregnancy?
