How long after implantation do I wait?

Allison

Okay so first of all, I’m SURE I’m overthinking this because I always do. 😂 I have 2 kids and my husband and I really aren’t trying for another, but we’re not being the most careful either. On Friday morning I had what looked like implantation bleeding (I’ve had it with both my other pregnancies too) on cycle day 23. Since Friday I SWEAR I have felt pregnant. Mostly lower abdominal pressure/kinda crampy. I just feel it. However I took a first response test today (which would be 3 days after I think implantation could have happened) and I feel like it’s clearly negative. If I was preggo it should be positive by now right? Thanks!
