Hi ladies

I've had a lot of the symptoms already mentioned, the main ones being nausea off and on throughout the day, and its now at the point where i nearly go to throw up. Fatigue, i've never been one to have sleeps during the day but lately i've been wanting to just sleep and going to the loo alot more. Also have some cramping pains and keep expecting my AF but im now onto my 3rd day late. The last test i did was a BFN so i really wanna test but worried its still going to be neg... i dont know wat these symptoms could be if im not preg...wat do u think?? I really hope to have good news soon!
