I am interested in anything anyone has to say on this...I would like to hear anyone's stories on this, however long they are.
I missed my blood test today because I got lost trying to find the clinic and I didn't arrive in time. At least I should know where it is now for next week. I was so nervous but at the same time I wan't sure if it was really worth it to spend the money, and here's why:
Last night I did a search online about this. Everything of relevance I found had to do with blood tests mostly. Anything about urine tests seemed to be the usual "explanations" that only apply to early testers. In passing through lists of questions, I also found a couple of different nurse-midwives and one or two doctors who said that some women do get their periods during pregnancy, some the first few months and some the entire time. So, apparently that's not as rare or improbable as is generally claimed either. Anyway, here's what I found on the internet about pregnant women with negative blood tests:
I found one woman who has posted a question somewhere asking why she never passed any blood or urine tests her first pregnancy. She took 12 urine tests and 5 blood tests her first pregnancy. The blood tests and 4 of the urines were at the hospital. You're not going to belive this, or maybe you are, but the doctor who answered the question basically just said the patient was probably not pregnant and it must be some other explanation that needs to be explored, completely ignoring the existing child that had come out of it! That was exasperating for me, so I can just imagine how the actual questioner felt. (In her second pregnancy, I think the woman got a positive urine test during the first month like people usually do.)
Then, I found an article about a woman with a molar pregnancy who somehow had HCG levels too high to show up on the test. It caused some kind of backlash or something.
I found another woman who refused to pay the lab for her test when the bill came and sent them a birth announcement instead! That was my clear favorite.
Two other women, on mesage board posts, were both menstruating each month, and had successful 3-4 months pregnant confirmations done by ultrasound when blood and urine tests failed to show pregnancy but doctors wanted to scan to explain their expanding abdomens and other pregnancy symptoms.
In addition, there was the woman I mentioned previously, who also had multiple late-false-negative urine and blood tests, and this covered two successful pregos and three miscarriages for her, all of which were apparently confimed either by ultrasound or by the obvious fact that she eventually gave birth.
No explanations found so far for any of this. Someone might suggest that the false negative blood tests were lab errors, but given that all the same women got false negative urine tests as well, it seems likely that another explanation exists and just hasn't been found yet.
I guess it makes sense to me that some people wouldn't shed HCG in their urine. But now I am wondering why HCG wouldn't show up on a blood test.
It seems clear that these people would need to produce HCG, especially since most of them could tell they were pregnant by other symptoms. HCG is the hormone responsible for the symptoms that make people suspect they are pregnant, isn't it? I mean, other than the obvious growing belly, it takes hormones to make all the other stuff happen. And, most of these people do have that stuff happen and that's basically the way they "know" in spite of their negative test results.
Interestingly, HCG is supposed to be the hormone that makes your period stop. I don't really know which hormones cause which other symptoms. But, a lot of these women have also said that they got their periods for months too.
Now I am wondering if I should even bother wasting 15 dollars on a blood test even. I feel like I should just wait another month or so and see. But, I am going to spend the 15 dollars, because I can't stand to just wait, of course. If it's negative then who knows what the heck is going on. I guess then I would have to see how much Planned Parenthood charges to check you out for fibroids and cancers and all that stuff with an ultrasound machine.
