I am 25. My last period was on 7th Jan. Since that, I started to feel sick after meals, giddy, nausea, cramping, mood swings, sore breast, lost of appetite. I had done 3 pregnancy tests n had even consulted gynae n an ultrasound had take place but result came out as negative. Am I pregnant?

Beside that, I realise that there are bleeding today (24 Feb). I was wondering is that my period or bleeding or miscarriages.
