July 28 he ejaculated inside me.i douched.he did it again july 30 aug 2 also.the othertimes he pullout.aug 7th is when my period due,can i be pregnant?

Definitely could: Douching does not prevent pregnancy, neither does pulling out. This is unprotected sex, do a pregnancy test if you miss your period. Good luck.

Take a test: With today being August 6 you ought to be able to take a test by now. Do you want to be pregnant? If so, intercourse every other day between day 9-20 of cycle should give you the best chance. If not, see your provider for reliable birth control.

Pregnant: Yes, you can be pregnant. Douching is not an effective form of contraception. If you do not want to get pregnant, use a condom!
