could i be pregnant but still bleeding heavily?

[ez1702]

i went to the doctors about a month ago as i was late on my period, they did a pregnancy test which came back negative, yet i still didnt come on for a few days, even when i did it wasnt heavy, then i started bleeding a couple weeks ago very heavy, with blood clots and more, i went to the doctors who felt my stomach and said he believed i may be pregnant and has took tests and is also sending them off, but i am still severely bleeding yet my stomach is growing and my breasts are sore and i have been throwing up, twins also runs in my boyfriends family, is it possible that i could still be pregnant if i am, or that the likelihood is that ive miscarried? has anyone else got experience of this.
