4 week symptoms ?

Okay soooooooo , my symptoms right now are light cramps , and gas . Feels like my stomach is going to explode cramps . And the (sorry I know it's gross ) but the diarrhea is off the chain it's like you're constipated and have diarrhea at the same time . Does anyone feel like they're going to start their period but obviously we're not ....  I have so many weird symptoms going on that its hard to know what's normal and what isn't 😩😩😩
