Feeling so dumb 🙁

I’m almost 2 years post partum, breastfeeding with no post partum period yet. Last Monday I had symptoms and a positive opk. At 7dpo I very light pink spotting (I haven’t had any blood at all since before I was pregnant with my first). I thought it was implantation bleeding along with cramps.

Today I took a first response and it was very negative at 9dpo. If it was implantation bleeding I thought I’d have a positive by now.

I feel dumb for testing, I feel dumb for symptom spotting, I feel dumb for thinking I could get pregnant the first time I ovulated pp, and I feel dumb for thinking I even ovulated at all.

Should I bother testing later or am I grasping at straws? And if I should test again, when??
