Could I be Pregnant?having weird feelings(like pressure or like it would feel if i were to grab my side) in my right side around the area of my appendix.

I have been ttc now for about 3 months. My husband and I have been having unprotected sex almost everyday trying to increase our chances. My period is extremely off all the time. Usually the cycle is about 50 to 60 days( not sure if that is anywhere near normal since it should be 28). I have been having weird feelings(like pressure or like it would feel if i were to grab my side) in my right side around the area of my appendix. Also sometimes it is on the lower left side. I took a test and it was neg but i accidently urinated on the other side of the stick(meaning the spot where it tells whether you are pregnant or not was facing down). I don't know if that matters or not. Like I said i don't know when I am supposed to get my period, i think my last was about a month ago and it only lasted about 3 days. I am totally clueless here any help is better than none!
