See if it becomes like a period for you. If not, try another test, using first morning urine, or see your doctor.

You'll have to decide how badly you feel. If you don't feel as though you can wait several more days to see if this is a period about to start, then see your doctor. They will do a pregnancy test there for you.

Okay well I had a normal period flow in march had multiple acts of sex that month before & after my period (never during ewww) April 20, 2012, comes around and all I got was spotting for 1 day that is it if it was a normal period flow it would have ended on the 25th or 27th of April but it did not... ever since 4/20/12 I been feeling off like not myself I have had an increase vaginal discharge, I've felt nauseous multiple times & puked four times on 4/26/12 while eating oatmeal I had one bowl went down perfectly fine then made another bowl due to me being hungry so when I started eating it I puked four times all oatmeal. Ever since 4/26/12 I have had light cramping, lower back pains, eating whatever I can find more then I usually it, Have had multiple cravings for mcdonalds food & spicy buffalo sauce and tangy bbq sauce.

See a doctor, as self diagnosing is not helpful, nor does it identify the problem, or solution. You are stressing over the unknown, so please see a doctor.
