It is 10 days BEFORE my period. Last month my period was 28 days late so my cycle has been very thrown off so god only knows when I am ovulating. I have had weird feelings in my stomach the past 5ish days. Sometimes it is light/medium cramping. I went to bed with it hurting on one side and woke up and it hurt on the other all day. I have definitely been going to the bathroom more often. Right now my stomach isn't feeling all that great. Smells are making me gag. I feel bloated all of the time. I had some slight redish/brownish discharge for 3 days. What the heck is going on? Would it be possible I could have gotten pregnant early in my cycle and I am feeling is before my period is here? Could it be something else? I have been with the same partner for nearly 2 years and were recently tested so I don't think it is an STD but what could be causing this?

Thank you for any helpful information.
