It Said Not Pregnant

Joy

So, me & my boyfriend had a pregnancy scare, well I’m still a little scared, my cycle was suppose to come on the 1st of this month till the 4th, today is the 7th & still no period, when I wipe, I’ll see a light red on the tissue, I been having cramps here & there, they only last about a good minutes, we took a pregnancy test & it said negative, should I wait a week to see if my cycle start before I take another pregnancy test or what??

Somebody Help!!
