Need answers...

The past few times after intercourse I have experienced pink watery discharge immediately after sex. I also notice some mild cramping within the hour. Has anyone else experienced this? Is it something of huge concern? We haven't been rough or done anything out of the ordinary. This has never happened before. I have not ovulated or anything yet this month. I just finished my period over the weekend, but like I said, this has NEVER happened before so I am ruling out my period as the issue. I have tried google, but I am not having any luck. Thanks in advance.
