White thick creamy discharge on my penius during intercourse but I didn't ejaculate?

[Playboicarti]

Okay so me and my girlfriend have been having unprotected sex and the past two times we did it we've noticed that there has been a thick creamy white discharge on my penius. I know it wasn't ejaculation because I didn't feel like I was going to climax at all. But I did notice that when ever I finger her she gets pain and I don't even do it rough just soft does that mean anything? She's also close to her period due date. Could it be the end of her ovulation? I know there's pre *** but it's not thick like this and it's spotty to it's in different areas of my penius. I know it's not ejaculation due to the fact that if I did it would be much more messier and I also did not go flaccid. What could it be? There was also no odor for what I know and it even showed up when we had sex for like 3 minutes and she wasn't even fully aroused yet!
