Tiffany

idk what to think...I didn't sleep with anyone for a year, then in april I got laid (yaaaay lol) I had sex on the 3rd period was suppose to begin on the 7th..3 weeks after it was suppose to begin I spotted, only when I wiped did I see any blood. next month, same thing but lighter, month after that even lighter. now in July I am a week late...I keep testing negative but my body is screaming that I'm pregnant. I haven't tested in over a month
