Cum or mucus plug?

Lastnight my husband and I celebrated our one year of marriage (WOOHOO)! Anyway we had sex around 930 lastnight, I used the bathroom right after, took a shower, went to bed woke up and took another shower. Around 2 o’clock I wiped and noticed a clear stringy jelly like discharge with a slight white tinge to some of it. It was a lot. To me looked like a mucus plug but no blood. I was having Braxton Hicks also after sex lastnight, currently 29 weeks unfortunately no picture but how likely is it it’s cum over mucus plug?
