DPO help

I got a positive opk on April 24th at 2PM. So I ovulated on the 25th. I had unprotected sex on my 4 most fertile days. I am now 2 dpo and I got a very sharp cramping in my lower abdomen. I felt the urge to pee really bad, followed by this type of CM. Clear & stretchy with white in it. Is this a promising sign? Never had this before, nor do I get ewcm, which is why I used pre seed each time I had sex in my fertile window. I have a very regular cycle so I know ovulation already occurred
