Totally un expected (tmi)

Jerressa

So this is unexpected considering these test were 10 days before my next period not sure if my cycle changed or what, but here's my next question me and my husband had intercourse I laid down after wards took a nap then when I got up to pee when I wiped I noticed very very light pink spotting is this normal could it be from sex ? Should I worry ? I have no clue how far along I am or nothing . My Dr app isn't until Thursday
