Possibly pregnant w/ boss’s baby

I’ve been sleeping with my boss since December and the last time we had sex we didn’t use a condom- I am on the pill tho and I’m pretty good about taking it so ik the chances of me being pregnant are small. However, I started bleeding yesterday and I’m not sure if it’s implantation bleeding or a period. Oh 🐳 I guess we’ll find out soon enough 🤷🏼‍♀️
