Signs that I am “in ketosis”?

Hi, Ive been on the Lipotrim diet since Wed, so Im just over day 3. How will I know I am in ketosis, I dont have the ketostix, the testers for ketosis, so is there any other signs that i might notice. I heard bad breath and a headache but are there more?

Had my sone five months ago and have had two normal periods since then. In the last six weeks i have lost three stone on the lipotrim diet and four weeks ago started back on my pill..Microlite. Since i started back on the pill on the first day of my period i was bleeding everyday for 18 days and then for the last eight days spotting and then today i am bleeding like a normal period. Went to the doctor and he said to continue on my pill as normal and then we'll see if it's a reaction to the pill and so on. has this happened to anyone and does it sound normal.
