Opinions, prego or stressed?

I am 3 days late on period. I have been extremely angry, eating every few hours and when i have to pee i barely make it to the toliet and even wet myself the short sprint to the bathroom. I woke up to day wit heartburn no ammoint of tums could solve then started coughing and all of a sudden i started salvating heavy and gagging, couldnt hold it down and toliet hugged and a mostly digested stomach. After i expelled my stomach contents i felt no heartburn and alot better oddly and was able to sleep like a baby since sleep is not coming easy the past two days. Opinions. No breast swelling or tenderness
