I know this could be completely normal, but...

What does this most sound like to you? I am 4 days late on my period. I've been having headaches, feeling exhausted during the day and keep waking up or having trouble getting to sleep at night no matter how tired I am. I keep worrying about little things as I lay in bed. I never want to eat breakfast because I feel sick in the morning (this is normal for me, not just right now), and then later I am STARVING and want to eat like 3x the amount of food as my husband (not as normal). I've been extremely bloated and my boobs hurt like crazy. I'm currently in the bathroom feeling like I'm going to puke/have heartburn. Sometimes on my period I throw up, get migraines, or even pass out. Last night my husband and I watched the movie Sully and I just kept having the urge to cry throughout the entire thing! I completely broke out all over my face like never before in my life! I totally feel like I'm PMSing so hard, but no blood yet. I've never skipped a period. Ever. I'm trying not to be paranoid, but a girl has to wonder. Does this sound like I'm pregnant, or just late? How many days late have you ladies been before you finally got your period? How soon is too soon to take a pregnancy test? My husband and I are excited to add to our family someday, but are using contraception right now (condoms). If I am pregnant I will be so grateful for that little unexpected blessing, but mostly I need to hear from you ladies and get an idea of what your experiences have been being late on your period/early in the pregnancy game. Please and thank you!
