Too early?

K🌻 • Married to my high school sweetheart. Boy mom. Ttc #2.
Okay, so let me just start from the beginning. I've been on birth control for 4 years. 1st year depo, next 3 year I was on the nexplanon. While I was on birth control I never had regular periods, mostly spotting and I would go months without a period. I quit birth control back in October and got my first normal period end of Feb. My fiance and I are TTC baby #1 and had sex every day a few times a day during me fertile week. (Now that I think of it I didn't even take an ovulation test, I was just going by what GLO said but I had the signs of ovulation.) I'm only 2dpo and have been having light cramps and when I wipe (tmi) I have a brownish color on the toilet paper. Could this be implantation bleeding? Or is it my body still regulating? The way I felt when I stopped birth control was amazing. I never knew that it was effecting my body so much until I quit and now it's so confusing because I don't know when my body is going to be completely normal again and the 2WW is just going to kill me.
