Implantation Bleeding

Hey ladies. We’ve been TTC for 7 months now. One miscarriage and a couple of chemicals. But this week I’ve been a little off. On 7/8 I was 11dpo and in the afternoon I had the lightest of light pink “spotting” when I wiped. I checked every time I went pee, and by the end of the night it was gone. Never needed a liner, only there when I wiped. Yesterday, 7/9 at 12dpo I had a negative FRER test with FMU. This morning, 7/10 at 13dpo I woke up with a massive migraine and nausea to match (usually because of the migraine), but had another negative FRER test with FMU. AF is due 7/12 at 15dpo. I’ll keep testing, but I wanted to know everyone else’s experiences with implantation bleeding. How long did it last? When did you get your BFP??
