Its very unlikely you are pregnant. As we age, we may skip a period here and there. If you are worried, you should see your doctor.
I hope she's ok, but I'm relieved she's in being monitored.
This is such wonderful news. You will soon be an expert in the medical field!
I think you are handling this so very well, and much better than I or most of us ever could.
We are all rooting for you guys. He looks GREAT!
It can be normal to have a bit of spotting after intercourse in pregnancy. The cervix in pregnancy is very friable, and tends to bleed easily.
It would be best to run this by your MD, since you are also having a bit of pain, too. It might be nothing, but its always best to let a doctor know when you are worried.
