it's 2 days before my time of the month I took a test and it was negative. going to wait a little bit. I purchased a dollar general brand test. I was almost positive I was prego. I have been feeling sick and sore breast for 4 days now so much so it's uncomfortable wearing a bra. I will wait to see if I'm late and test again.
