No AF yet

Lauren • Just got married, have an almost two year old and trying for another sweet little baby.
AF is 1 day late now. I had some cramping a few days ago and thought that AF would be there the next day but didn't show up. I was up last night at 4:30 am puking(not sure if I'm pregnant or something didn't agree with me... Will someone give me a little advice on what to do :(
