My last period was march 19 and i still haven't came on my period this month.and it's the 26th.i have a regular cycle. do you think i may be pregnant.

Maybe. Maybe not.: Pregnancy is the most common cause of a missed period. If not pregnant, other causes of a late or missed period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (especially birth control pills), hormonal disorders, etc… A home urine pregnancy test gives a reliable result 3 weeks after sex.
