feedback anyone ? Im worried

Okay so today makes Day 3 of my missed period. I've been very moody, emotional and irritable. I have been crying for no reason, wanting alot of attention, I feel cramps in my pelvis. My boobs have been tender for about 4-5 days now vey fucking tender. They hurt whenever I touch them. My nipples are very erect and usually they arent and they itch kinda an annoying painful itch. Is this normal ? No spotting has occured anything
