Symptoms or crazy lady?

I had AF on the 13th of Jan. My SO and I had sex from the 16th-25th everyday. I'm assuming my O day was maybe between the 21st and 25th. A few days later I was having very very mild cramps. I thought maybe gas lol but it wasn't. I also have had some light nausea but no vomit or dry heaving. Just yesterday I noticed my breasts were kind of sore. I'm hoping to get implantation bleeding soon or some sign that there's a little me in there. All my pregnancy test are negative but I have realized I'm testing too early. I'm hoping to get a faint line between the 5th and 11th and hopefully no AF.
