I sure am getting my money's worth out of the nurses this cycle. I spoke with a nurse for about 30 minutes today. The bleeding could be a number of things:
1. Implantation bleeding-yes, it is possible for implantation to occur this late, or for the embryo(s) to just be burrowing in further. The process apparently takes weeks. Who knew? Plus, the nurse said that because we get hormones in spurts from the estrogen and progesterone support (rather than the constant supply that would occur in a natural pregnancy), it tends to make the uterine lining a bit less stable than it normally would be.
2. Impending period trying to break through even with the progesterone support
3. Irritation of the vaginal wall from the prom.etrium. If pregnancy is confirmed, they suggested switching me to endo.metrin which may not be as irritating.
4. Small, or beginning of, a subchorionic bleed (separation of lining from uterine wall). This can be diagnosed through ultrasound, but they don't see the point of doing this until a pregnancy is confirmed and the recommendation is always bed rest on hope it heals on its own. It can't be fixed.
The nurse said that if I was really worried, they could have me come in for blood test today, but it is still a bit early so she recommends we wait until scheduled blood test. I didn't push it.
Because of the possibility of number 4, I've been ordered back to bed rest through the weekend. Not as strict as post transfer, but lay down as much as possible and no vacuuming, laundry, etc. So I packed up some work to take with me and now I'm hanging out at home trying to get some work done and hoping with all my might that number 1 is true.
On the plus side, the spotting appears to have subsided. At least for now.
