Thank you all! I still can't believe it.
I recorded my symptoms faithfully this cycle even though I wasn't trying to "symptom spot" myself to death. Anyway, here they are by my best calculations as I didn't use OPK and I didn't temp. I mostly just tracked cervical fluid to know when I was fertile and had a day where I'm pretty sure I ovulated due to some specific pain during the day on my right side. Here are my symptoms by dpo:
1 dpo - nothing
2 dpo - headache and increased acne
3 dpo - boobs started hurting around sides and armpits (my boobs usually hurt with AF but this was much earlier)
4 dpo - woke up dizzy and was dizzy throughout the day; sore bb; felt bloated
5 dpo - headaches; light nausea; sore bb; crazy dreams
6 dpo - sore bb; gas (sorry, TMI)
7 dpo - sore bb; horrible cramping at night (implantation?)
8 dpo - sore bb, diarrhea; crazy dreams
9 dpo - sore bb, gas, mild cramping; crazy dreams
10 dpo - sore bb, extreme cramping, diarrhea; tested with dollar tree test with BFP! Confirmed with FRER
Biggest clue was my sore boobs. They felt different than usual. The pain was in different places and at times they had sharp pains when nothing was touching them.
Hope this info helps others!
