i was on birth control for a couple of years, & i stopped taking it last month because my partner & i are ttc. i ovulated 6 days ago, & then 3 days later i started to spot. i know that's super early for implantation bleeding but idk what else it could be?? unless it's from me stopping my bc. tmi, but it was a brownish color & lasted for 2 days. tomorrow i will be 7dpo. when is the best time to test??
