Hii, well let me just start off with my period last week... I normally have a 27-28 day cycle and It lasts 5 days and is extremely heavy at first with clots. Well my period this time was lighter than normal, and no clots really and lasted 3 days then stopped completly for a day, then around dinner time the next day came back for and hour and then was gone. Well a couple days later I started feeling sick and slight weird cramping and I've been tired a lot, and headaches almost every day. Id get a fever on and off through out the days. It's currently day 7 and I'm bloated and I have a loss of appetite and also weird slight cramping on and off and if I press on my lower ab. I feel sick for a minute. I have had unprotected sex a little over a month ago. Oh, and I've been very moody. I don't know if I could be possibly pregnant. I need some help.
