Second period this cycle, withdrawal bleeding, implantation bleeding???? Help !!

Hi ladies!

So I’m having some trouble here. My husband and I are trying to conceive. I got my period July 6th-10th. It was pretty normal nothing out of the ordinary. I got off my birth control a few days later, mid pack (because I’m stupid I know🙄) And had four days of withdrawal bleeding. My period isn’t supposed to come until August 10th/11th, and supposedly today’s supposed to be my ovulation day.

However as I’m sitting on the beach on vacation- I had some leg cramps and felt some liquid come out. I checked and saw some brown so I went back to our house to check and pop a tampon in. But there were two nickel size brown spots, and the rest was pinkish watery liquid set into my bathing suit.

Do we think it’s an early period??? I don’t want to get my hopes up 😩
