Maybe pregnant??

Has anyone experienced this… we’ve been TTC for 6ish months now. Like clock work, I’ll ovulate, immediate breast pain and swelling until my period starts. This month, same thing but about 8 dpo my sore breasts stopped and 9 dpo I had light pink spotting (very little amount) Today, 10 dpo I am having very light brown spotting. My breast tenderness hasn’t came back yet either. The change from my normal pms routine and the spotting makes me wonder 👶🏻

I tested this morning and it was negative and I am 4 days from my period!

Anyone else experience something similar or have thoughts on this?
