Feeling full and Nausea

just yesterday til now i've been feeling like I don't have much appetite, nausea, feeling full and my tummy keeps on having borborygmus (or is it called spasm? like i hear noise from my tummy, even if i've eaten already), sometimes my tummy hurts like for 1 or 2 minutes, like you feel you're going to defacate, then will occur after few hours, or when i eat or drink something. then i kinda kept burping or having gas.

just for your references/infos:
-The last thing i remember that i ate was yogurt and a certain food that has raw onion...and i've been doing crunches twice a day for five days already.
-had my period 12 days ago.
-having allergies lately
p.s. I never starve myself nor skip meals just in case you might ask

Hi there!

Well, without a clinical evaluation it would be difficult to determine the cause of your symptoms. Likely possibilities include gastritis, GI infections etc; even though your have been taking adequate precautions on your side. I would suggest an evaluation by a primary care physician for an accurate diagnosis and appropriate management. Meanwhile you may try taking some cold milk or OTC NSAID and anti-emetics and see if these help.
Hope this is helpful.

Take care!
