Did I miss my window?

So yesterday all day I got BFP LH tests ALLLL day 🤗 (see right strips) BUT I wasn't able to BD yesterday or last night and did at 5:45am this morning. I took my LH test at 6:15 and it's  barely there (see left 2 strips) did I miss my window? Also should I BD again tonight and tomorrow or just tomorrow? This is my first month TTC after being on BCP for 18 years so I'm new to this. I'm just hoping it wasn't too late😁
