Okay so, my period is supposed to come tomorrow (i REALLY hope it doesn't) lately I've been stuttering and messing up my words so bad! (Did it with my first pregnancy) I've had weird cravings (one being mustard, which I HATE) I've been super emotional (cried because some grapes we had were moldy so my son couldn't eat them) I don't know if I am actually pregnant or if I'm just super PMSy and I'm looking for symptoms. It also says that my days for conception were 3/25-3/29 and we had sex on the 25th. What do y'all ladies think?
