On the 19 of August I only had my period for one day but I had really bad cramps and lower back pain, so I went to my Dr. and he schedule a ultra sound just to make sure that every thing is fine. I got my period again on the 19 of October only for 3 days (when I usually have a long period.) so I went this Saturday to get an ultrasound and when they did the pelvic the tech notice that I had just had my period a couple of day before because I had (left over molecules) and she did not see any thing wrong. But as soon as she did the Transvaginal she spotted something that looked like an egg she said that I could be pregnant !
:p but that I should wait a couple of weeks before doing a test because its so small that it dose not even have a heart beat yet.. So am I really pregnant? What should I do ?

I really want to be pregnant. So should I think I am yet or should I just keep trying to get pregnant ?

If they saw it on the ultrasound, then the test should show whether you are pregnant or not.
I tested positive at 5 weeks pregnant, 3 weeks gestation. The internal ultrasound showed only what the tech though might be the egg, but it took her a few minutes to locate it, and she knew she was looking for the egg, because I'd already had the urine and blood tests come back positive.
Hope this helps a little.

I think you should keep trying thinking you pregnant its nothing but doing things to get pregnant can help
