Strange light pink watering spotting?? NEED ADVICE!

Elle • Trusting in God's timing while hoping to uplift others. Baby #1 with Jesus. He's not finished with me yet.
So I'm two days late and was planning to take a test tomorrow. Was pretty certain I may be pregnant because I was experiencing strong symtpoms I've never experienced before (morning naseau and light headedness, cravings, etc). However my husband and I just had sex tonight and when I went to wipe myself I saw this light pink watery very light first I was shocked...huh??? My period??? I don't even feel my normal period symptoms?? But then I realized I've never had anything like light pink and so lasted maybe 5 minutes?...should I even test tomorrow?? What is this??
