7 days late

Hello ladies! I have a regular 26 day cycle. The only time I have missed a period was when I was pregnant. I have been having on and off dizzy spells, nauseous on and off everyday and have vommited a few times. My breast hurt more than ever in my entire life! (No exaggeration) I mean clothes make me cry, the shower makes me cry. My nipples are swollen and very red and my breast are swollen I don't fit in my bras, my breast hang out of them. Lol. My veins are more visible than ever. They just hurt and everyday I think about how to get rid of them. My back is just as bad as my breasts. I work retail, which means I worked Black Friday. Lifting and just standing Was enough for me to almost quit, I was in so much breast/back ache I left crying. I am always tired, it doesn't matter if I slept 10 hours I feel as if I only slept 5. My moods are on a roller coaster. I cry and have no reason, I am angry over the silliest things, than after feel stupid about being angry. They are just a mess! My eating habits before this were I ate a few meals a day with snacks. Now I eat about the same amount, but I eat things I normally wouldn't even have.a thought of eating. I actually crave. My bbt has been slightly higher. My normal temp is 96.8, it is averaged at 98.3-98.8. Does this sound like I am getting sick or pregnant? Should I call my docotor?
