Clear sticky discharge

Hi,I'm hoping someone will help me with this... I have had unprotected sex with my partner a few days ago (2-3 days ago) but just for a while,I'm sure he precummed in me because he was at the point where he had to pull out but he didn't and tried to not cum in me_so i personally am sure he at least pre cummed a little bit.I'm not convinced that i am pregnant,i just find this strange that what has happened after that,has started happening right after we did that! Well,this morning i woke up from a dream with stomach pains that is very sore and it went from the middle to the left side for a whole while,paining like hell,and after a while of that,it just stopped,just like that,i was surprised about it myself,i went to the bathroom to wee and i saw this slimy looking stuff coming out of my vagina,i stuck my fingers in and as i looked it was clear and it was sticky,i am not sure what is was or is in fact,but im hoping someone will tell me what they think it is,also,Ive noticed that the pain has not completely gone away,its still there even now as im typing,i can feel it and it nauseates me a bit actually and it not period pain,well i don't think so because when ever i get period pain its not painful from the middle to the one side,but rather from both sides and its normally a sharp strong pain like muscles contracting all the time,it never goes away and the pain does not lessen,this what im having is different,im not so sure what it can be,can anybody tell me?
