I know some women say they do but how possible is it to feel symptoms before implantation or missed period? I am currently 7 dpo, this morning I had these weird pains in my pelvic region that I have never had, I feel like my breasts are on and off sore. and the other thing is headaches. after my last child, I ended up being hospitalized because I had severe migraines, I used to get them once a week or so and eventually it became just normal headaches on and off 2 maybe 3 times a month. but I have literally had a headache since Sunday which would have only been 2 dpo. am I crazy or is ir possible that these are symptoms this early?
