Ttc #2

I have some questions even though I’ve been through this before

1. When i had my first kid i had a bfp a week after my missed period although the day of my missed period i “bleed” brown for a week!

-also miscarried before my first kid and had implantion bleeding “one spot of blood on tissue” same day as bfp carried it for 8-10 weeks

“Do you have implantation bleeding every time your pregnant if you have it the first two times?

2. I never got an early positive just on or after Missed period. I’ve been testing like a crazy lady since 6dpo this month (i know I’m crazy)

“Does some ladies never get an early positive before their missed period?”

& 3. My opk surged on cd 19 “Jan 5” and then lowered that evening and back up again on Jan 6th.. i had sex according to first surge.

“Does that look correct?” Pics attached
