I'm 22 and I haven't had a period since Dec 19. I took 2 home pregnancy test and they both came back negative I took one at the Dr Office last Thursday and it was also negative. Is there a possibility I could still be pregnant? I pee constantly no sickness, just cravings and weight gain. I am usually pretty regular give or take 3-5 days. I have heard of women who go 13 weeks without their HCG levels showing.

Have you discussed this with your doctor, or obgyn? It could be some other underlying issue and not be related to pregnancy at all. But I'm not a doctor, so I'd recommend speaking with one. Possibly second opinion if necessary?

I've talked to my dr. and they just keep telling me to come back in two weeks. The only thing they have done so far is give me a urine test. Grrrr they are really starting to get on my nerves. I would really just like to know because my brother and his girlfriend smoke in their bedroom at my house and if I am pregnant I want them to stop not to mention I drink wine and I would like to know if I need to quit doing that also

I would ask the doctor's to run a blood test on you to see if you are pregnant.

Regardless of whether you may or may not be pregnant, I highly suggest you stop drinking. This is far more dangerous than second hand smoke, although it isn't good either. Until you know for sure, whether with blood test, second opinion etc, I would avoid the smoke (or get them to stop) and stop drinking, just to make sure.

I would strongly suggest treating your body as if you are pregnant until you find out for sure that you're not. So the wine would be off limits.

In the meantime, if you're really concerned, ask the doctor to perform a quantitative blood test. It will look for any level of HCG in your blood stream.

What kind of home pregnancy tests did you use? Each one has a different minimum level of HCG.
