Early pregnancy gas :( ouch

So I'm estimated at 4w+5 and my dominant symptoms right now are gas and bloating. Fun stuff. Up until recently, it hasn't really been a big deal. However, I did a bit of yoga last night and ever since I have been coughing up mucous (2 tiny specks of blood in it last night immediately after, which may or may not be anything at all)and I've also been uncomfortably bloated. Like all day I've felt like I can't take a really deep breath. This morning the gas was coming out, but now I just feel like my abdomen is extremely full right up to my sternum. It does hurt a bit, too. Mostly just little pains all over my torso. The coughing has stopped as of about lunch time.

Sorry about the wall of text. Is this normal? Can I do anything to get a little relief?
