Jelly after sex? Possible TMI no pics

My husband and I have been trying to conceive for nearly two years, I'm starting to think it's me :( He has a child from a previous marriage so I know he can make babies, but I've never had a baby so I feel like the problem. Anyways, we did the deed today and aftwards during cleanup I noticed this jelly looking stuff? I'm not sure if it came out of him or me but I've never seen it before, does anyone have any experience in this? Could this be what's preventing me to get pregnant and I've just never noticed it? He's my only sexual partner and was my first so I know it's nothing like a std, any thoughts would be appreciated! :-)
