If my husband took his condom off and put it inside me can i get pregnant? we're trying to but he last longer with one on

Yes: Any stimulated/erect penis will be leaking secretions that contain sperm.The main load has a higher concentration, but all secretions can do it.

Pregnancy: Did he put his penis or the condom inside you? If penis remains erect and there is still ejaculate on it, pregnancy is possible. i suppose if the condom is placed in the vagina inside out, this could allow sperm to enter the vagina.
