TMI: CM PICTURE: EWCM OR SEMEN?

We DTD around 3:00 and I just checked CM. Not sure if it's EWCM or leftover semen. I rubbed it between my fingers multiple times and it didn't break. I know it's most likely ewcm, but is it possible it could also be semen? We have been ttc for 5 months but avoiding this month due to future work schedule. But now I might possibly be ovulating early?! 😁
