Is this amount of leaking normal?

Bree

I am 33 weeks and 3 days pregnant & have occasionally been leaking colostrum since about 20ish weeks. I’ve usually had the spotting type leaking like on the one side but never one giant leak spot like the other. This happened in my sleep last night. Is this a normal amount at 33 weeks? Also, I have had a cold the past few days and my cough started getting worse yesterday so I’m wondering if maybe having a cough could cause leaking?
