Some fluid can be normal, depending upon where you are at in your cycle. I have seen woman have a bit more fluid after having an endometrial ablation done.
However without further testing, the fluid could be anywhere from clear fluid, fluid consisted of blood or even pus.
I know you have the pain and if I recall, you had some cramping and unusual bleeding as well. One thing that does come to mind is what's known as adenomyosis, which can produce fluid in the wall of the uterus. You can read more on this here. Click here
You may however have to further investigate to confirm what the fluid is and go from there.
Hope this helps Hun.
When is the last time you had your period? Was the flow normal?
It's very possible that since you are producing these cysts, especially since there are more than one. Your uterus may be producing high levels of hormones, causing the fluid. Another possibility is a blighted ovum, which happens when a fertilized egg attachés itself to the uterine wall, but the embryo does not develop. It should only take a day or two for you to get the results back on the blood test. If you are producing high levels or hormones, this can explain the cysts and the fluid. But I still think you should find out what the fluid exactly is, especially if the test does in fact come back Neg- as once you find out what the fluid is, then your doctor should have a clearer picture of what is going on, as you can't just assume it's amniotic fluid.
Keep in mind I haven't seen the ultra sound nor seen the reading of the ultra sound either.
But there could be a thin, hollow tube that is inserted into the vagina and through the cervix, needle (such as what they do when one has an amniocentesis. But this does depend upon how much actual fluid is being indicated etc.
I don't know if they also did a full blood work up checking blood counts etc, as this can indicate if there are any type of infections occurring as well. I would be very curious in seeing the radiologists report on the ultra sound.
Otherwise, I think this is going to be a step by step in determining course of action. Did your doctor say what her next step is, especially if the hCG test comes back Neg-?
The birth control can help a lot of woman. However, it can also do the opposite as well. I for one couldn't take the pill, as it caused the cyst to become larger and stay vs bursting. So do beware of any cramping and/or pain you do get.
Either way, do keep me posted and I do hope all works out well.
Best of luck Hun.
