FTM and wish there was a clear answer 😆

Im 40 weeks today. I was laying down, felt some fluid come out. Went to sit on the toilet. The fluid that came out was pink, but only like 3mLs amount. No contractions, I havent felt any this whole pregnancy yet. Midwife on call says to put a pad on and shes not concerned if it doesnt leak through considering ive got no contractions too. Hospital is about an hour away. I was almost sleeping when this happened so she advised me to drink some water since i havent felt baby in a while as well.

Is pink tinged fluid normal?

Anyone able to tell me what to maybe expect?

Edit: after looking into it, I think it may have been my mucous plug.
