CRAWLING OUT OF MY SKIN!

Ok ladies so I am 10 DPO and have just been having an awful time with mood swings, bloating and nausea. I just recently got back on Nuvaring, but these past few days I have just been bawling my eyes out over the strangest things. I am not one for sobbing at random, but these past few days I have cried more than I have in three months. I am having very dull cramps like a light pinch and my tummy has been super upset. Do you guys think I might be pregnant or nah??
