What’s the difference between Pregnancy cramping and Period Cramps? Is there a difference at all? I dont mean like full blown period cramps, but like ones you get before you start.

What’s the difference between nausea due to pregnancy and due to gastritis?
is there any difference? i’ve been feeling this nausea almost whole day and when i pressed my gastric, I didn’t feel pain like what I used to feel when I had gastritis.
what i meant was i haven’t taken any pregnancy test yet and 3 days late…so i’d like to know if this is gastritis or due to pregnancy?
and please don’t say.. go to doctor or do a pregnancy test
