I really need to know if I am pregnant,had intercourse on the 27th of October, had my period but since then then I had sensitive breasts dizzy,nauses, tired. Had sex on the 30 November 2010, I had to start my period the 1st of December but was 5 days late, I now have cramping, and started with a brownish discharge bleeding that went on to heavy bright red/Pink colour with some clots and is getting less now, my breasts are still sensitive, I have dizzy spells and feel nauses at times. Please I need an answer did 3 hometests all negative

It sounds more like you really need to go to the Dr.

Because you had both periods and negative pregnancy tests I would say it sounds like you are not pregnant. However, you are obviously upset and not feeling right, so perhaps you should explain this to a doctor.
