Yet another cm question

cassafrass • .
Currently I am not ttc. My period ended on the 3rd and my SO and I had unprotected sex the 4,5,6, and 8...my sex drive was insane. Yes that was stupid but we already have a 3 year old and an unexpected pregnancy wouldn't be unwelcomed since it took us so long to conceive our son. Anyway according to glow I entered my fertile week yesterday and had been having cramps for a few days beforehand. I haven't had any ewcm but today I had light brown tinged creamy cm. Could this be related to impending ovulation or another cause in your opinions?
