cramping day 20??

I'm cramping today on my right lower pelvis side and it's day 20. I got a LH surge on day 12 and had sex day 12, 13, 14. Could this be a sign of pregnancy or am I just hoping and reading into this? I'm 31, I have a 12 year old but got married a year ago and we have been TTC for 11 months now.
