Ok, I recently have gotten my blood work done to check my HCG levels and I got my results this morning. It went from about 5000 to about 9000. It went up, but did not double. I've also had a transvaginal sonogram done last week and they found nothing, not a sack or anything. I'm having a second transvaginal sonogram done to take a look again. All while this is happening I've been bleeding and cramping etc. which is why I've been having all this testing, because I've possibly had or been having a miscarriage. It's possible I'm not as far along as everyone is thinking, but I just don't know. Any thoughts about all this?
