Signs of pregnancy. Weirdest thing just happened

Today I am suppose to start my period. No signs yet. I have had cramps for probably a week and my breasts have been really sore. The cramping isn't normal for me that much before my period but kind just shook it off. I had sex multiple tkmes with my fiance on fertile days. I took a pregnancy test at 10 dpo that was negative... but no perood yet today and the weirdest thing just happened.

I am at work right now and was at the fax machine and suddenly felt dizzy like i was going faint and had a severe loss of balance. The world was spinning. so Weird. Now, I'm sitting in the bathroom trying to get myself together and feeling like I might puke. 10 dpo maybe too early then? I'm thinking what the hell is going on lol
