I took a pregnancy text a couple days ago and it said negative my A'F still hasn't came yet. my period was suppose to come 1/18 and hasn't came yet. and last night me and my hubby did BD and afterwards I had a little bleeding when I wiped but once I wiped again there was nothing. what does this mean? it's been almost a week missed period.
