Am I overthinking???

Okay so glow says that AF should show up today and usually I'm spotting by now. I had a laproscopic surgery on 12-30-15 and I have a runny nose that started earlier this week (my best friends first sign was a cold) along with sore breasts and creamy CM today. I havent had any cramping or anything other than the sore breasts that might indicate AF! My husband says he doesnt think their is any way im pregnant this soon after my surgery...Am I just overthinking this or do you think I should take a test??? I don't want to get my hopes up just to be let down again :/
