Pregnant?

Period was supposed to come today, or tomorrow. I have cramps since yesterday, I never have cramps before period, only when it comes, the first day.

I feel a dizzy and yesterday, for 5 minutes, kind of...I had a hot flash and sweat instantly, nausea...I never had those.

And today...no sign of cold or flu to explain the hot flash.

We only use pull out method.

What do you think?
