12 DPO

Ana

I’m 12 DPO and am having light cramps on my left side for about 2 days. I always cramp on the right side before AF so I’m wondering if it could be a sign of implantation or pregnancy? I’m also having extremely sore boobs, I think a bit more than usual (but I could be symptom spotting). And I’m having very vivid dreams … I have tested this morning and it was a bfn.
