Could i conceive in a hot tub?

me and my fiance were having sex in a hot tub, unprotected obviously, and the hot tub was only at 100 degrees. He ejaculated into me and then kept his penis inside of me for a good five minutes. (We were in the missionary position BTW) So even tho water could have killed some sperm as well as the heat, or the fact that water could have washed it out when he did pull out, could we still conceive? i ovulated the next morning.
