Implantation symptoms

Sara • 8/24/14 👧🏼 .. 2 angel babies 👼🏽👼🏽 .. widowed 💔

Wondering what’s the earliest you have experienced implantation symptoms? I’m only 5dpo.. I know it’s “too early” but I had an awful headache this morning and have had this sharp pinching pain on my lower right side. I tracked my ovulation this month with OPKs and checked CM. We used preseed 3 times.. I feel like we did everything we possibly could to conceive this month.. just really hoping this is our month. If I don’t get pregnant this cycle my OBGYN wants me to come in for testing as this is month 12 of ttc.. just wondering if anyone else has ever experienced this and got a bfp??
