Peins touched vagina. took morning after pill levonorgestrel 1.5mg . after 6 days got heavy period for 7 days. could i still be pregnant?

Not likely: I am not a Obstetrician / Gynecologist, so first you should go to whoever prescribed the levonorgestrel & ask this question in person. From your description, I think the bleeding is from withdrawal of levonorgestrel with a contribution from your usual menstrual cycle. Generally, with such bleeding, pregnancy is unlikely. You could check a home pregnancy test just to be sure.
