I'm 8dpo, and ever since the day after I ovulated I swear I felt like something has changed (I know logically it was too early) but I had a mild but consistent cramp on my lower right abdomen, nauseous, emotional, peeing a lot, and just had a "gut feeling" that this might be the month. Now I'm suddenly feeling what are more like pretty severe period cramps (like doubling over), but AF is not due until the weekend so it seems too early for it to be that, but I feel like I suddenly lost that "gut feeling" now too. Any thoughts, and do I sound completely crazy?
