ER Visit


I was in the ER 5 days ago for what they think was a stomach ulcer (also found out I had a UTI) I was already 5 days late at this point but my pee tests had been negative and the blood test they did was negative, but I still haven’t had my period (10 days late now). I have never been this late, but I assume that all the tests can’t be false negatives... Has anyone experienced a missed period from a stomach ulcer? Should I take another pregnancy test?? Help!
