Help ?

So me and my boyfriend have been trying to conceive for a couple months now . My period ended on sep 5th and 6 days after on sep 11th me and him had sex and he did finish In me . 2"m we will do the same .. Is there any suggestions ? Or can I get pregnant this way . I heard you ovulate after your period as well . And since my periods are irregular I know I would try harder to conceive now . Can I get pregnant ? Yes or no , can any one help ?
