My period is 38 days late I've taken one otc test which was negative. Last period 4-8-15 had pinkish spotting on 5-15-15 and 5-16-15?

Repeat test. repeat in pregnancy test on first morning urine at least a week to 10 days after your last test. If both are negative then unlikely you were pregnant. Would wait and see what happens with next menses. If again no menses then need to see your doctor for examination and testing. Hope this was helpful. Best of luck.
