i might as well just say it all and hope someone can help with answers..
I am 1 week late on my period before i missed it i took a test because i felt that i was but it came back neg. then 2 days after it was due i took one and it came out neg finally i called the dr and went in since it was 3 days late and it also came out neg.i also had a pain on my left side so the doctor told me to do an ultrasound and see what was going on. while i was doing the ultrasound the dr and ultrasound tech told me the uterus wall was very thick and there was a small sac meaning there could be a pregnancy. after i was told they drew blood and told me to call the next day for results and i need it was also neg. i asked the doctor why if the ultrasound had shown something and he said it could have just been a mistake. i know what i saw.. i am very confused and still dont have my period can someone please give me any advice. we want to be pregnant! email me at carmenmmrojasaol.com

Hey, I have some advise for you that might actually be good....... GO TO ANOTHER DOCTOR.... PLEASE....My cousin had the same situation and she went and got a blood test and everything that came back negative she actually waited until she missed 3 periods and when she went to the doctor at that time the test came back positive. Just for right now wait but if you can go buy some prenantal pills from your local pharmacy and take those just in case you are you already have a healthy start.

A second opinion would be wise; seeing that you're not comfortable with the first one.

Maybe you're not pregnant... maybe it's some kind of growth ... who knows?
Definitely see another doctor--- make sure it's an ob/gyn and not a general practioner.
