I got my period but I’ve gained weight

So ladies when I was supposed to get my period I was about 1 week late and Then before I was supposed to get my period I had pee in my blood . But I did end up getting my period . Honestly I have no pregnancy symptoms but I have gained weight in my stomach area I haven’t took a test but I did take a test when I was the week late and came out negative and then I got my period . But I am getting this discharge idk if that cold be a sign . My period isn’t due for another 12 days !
