Ok ladies I've been having all the symptoms of my period except ! I keep smelling weird things but it's been 3 weeks since we had unprotected sex . It was totally unexpected totally out the blue but I'm very fertile so I was scared I might get pregnant! Well I went ahead with my instincts and took three 7$ pregnancy test. What do y'all think??? I have a one year old but when I took the test for her they came out very dark . I took these in the morning on Tuesday! Shoot your opinions , bored and curious!😅🙂🙂
