Vvfl?? Tweaks welcome!

Ttc for my rainbow baby! Had a m/c at 13wks in late sept, egg implanted but fetus never formed. Body took 13wks to realize I wasn't pregnant and naturally m/c'd, but hpt were coming up positive up until then. Anyways! This is my second cycle back and 1st using opk and preseed again (that combo got my last bfp after 4 cycles of ttc before hand). Used to use cheapie opk's but this time used clearblue advanced and went from low straight to solid smiley on 12/24. I'm a terrible symptom spotter but today my tummy has had a "tight" feeling, light cramps sort of. But I took these suuuper early, 8dpo but in person I swear I see a tiny vvvvfl! I was trying to capture it to show I wasn't crazy!! Yesterday's test was definitely blank.
