Coffee Drinks @ 6 weeks pregnant

Tee✨ • Somebody's Mommy
Okay guys I'm in a little panic here. I bought a medium Carmel Frappe from McDs. After drinking about a fourth of it I started spotting light pink. Although, This isn't the first time I spotted this week and I know you're not suppose to drink as much coffee or caffeinated drinks while pregnant. Should I worry or is this just a coincidence ?? This is actually my first caffeinated drink since being pregnant. ... & my first pregnancy so that escalates how worried I am. Have you had this happen to you??
