My periods are like clockwork always 28 days apart and always 6 days long. My last period was 3 days late and only 2 days long. I keep track of my period and when me and my fiance do the deed and notice we did it 3 days in a row during my ovulation time. I've been having weird symptoms also like nausea, strong sense of smell, back cramping and sensitive breasts..... I have 3 kids already and they're 12, 9 & 7 so I don't remember what it was like to have the pregnancy symptoms. Could I be pregnant?
