Ok so if I have this right, your getting married to this guy that your parents don't want you to see and or have sex with. That really sucks that you miscarried, but maybe thats for the better, look at what kind of life it would have come into, would it have been the best? How can you not be sure that your 5 to six months?! Shouldn't you be showing at that point? Unless you are overweight (no offense if you are). If all the tests are saying no then you couldn't be that far along, you need enough hormones to support that baby in the womb. And those tests are VERY sensitive, they'd pick up the slightest hint. Have they done an ultrasound? If there is a baby in there they could see it, if your not, they could see what is giving you those weird sensations. You might be getting those signs because your body still thinks there's someone there. You have done all you could to prove that your not, with the exception of the ultrasound. Get that done, if its negative, then you need to be talking to a trusted doctor about why you have these symptoms and what, if anything, you can do to fix them. ABout the weight, I don't know. ASk the doc. ANd dont be afraid to get more than one opinion 2,3,4...! Let us know if and when you get this sorted out.
