Pinkish discharge 2 days after sex...advice or suggestions?

I have not experienced this before. Its looked like the man's 'you know what' but had a pink tint to it. Like when u use the bathroom after sex and some of his stuff comes out when u Pee. Sorry for tmi. I'm not in my ovulation period but it was about 5 days after my period ended. Anyone know what it could be or ever experienced this before....then found out you were pregnant? We have been trying for over 3 years so it would be such a dream come true!
