My periods range from 28-52 days but normally around 42 according to my chart my fertile days ended 14 days ago. I tested maybe 3-5 days ago saw a faint line took another in the morning and nothing. Could I of tested too early? I had period cramps but they went away out of the blue after having them for 3 days (they were worse than normal ) all yesterday I was nausea and my nipples were sore. (They usually are around af) do you think I have a good chance of being pregnant?
