Tired

I'm now 30 weeks along and the tiredness is coming back. We've had some unexpected things come up and I think the emotional stress adds to the fatigue. They are still wanting to monitor the baby's kidneys which are both still enlarged. The cutoff for normal is 4 and his are at 6. If they reach 10, they will have to do a test where they insert a needle into his bladder to test the concentration of his urine. If that comes back abnormal, it means that the kidney has reached the point where it is not functioning properly. If that were the case, they would deliver him then. My next u/s is in 4 weeks so I would be 34 weeks along. The idea of the test makes my sick to my stomach since I know that he would feel the procedure. Add that to having to deliver him early and it's pretty stressful. I just want my baby to be okay.
On top of that, I noticed a small black mole on my shoulder about a month ago. I went to my doctor to have it looked at and he recommended it be removed. That was done a couple of weeks ago. T"he pathology report came back that although they were holding back on calling it melanoma, that they were recommending it be treated as one and that more of the surround tissue be removed. The surgeon said that if left alone, the mole would have developed into a melanoma. So, yesterday I went and had an area of skin about the size of a ping pong ball removed. He ended up having to give me 5 stitches. It's VERY sore today. I wasn't expecting it since the first procedure didn't really hurt. I saw my OB this morning and she was surprised they didn't give me anything for pain so she gave me a prescription for stadol. I'm trying to hold off on it though. Now I have an appt with a dermatologist in 2 weeks. I'm really nervous they'll find more spots. I'm just feeling a little overwhelmed right now.
Anyway, I'm trying to focus on the positive right now. Baby boy looks great other than the kidney issue. He moves constantly and I love it. My OB asked if I was tired of being pregnant yet and I can honestly say no. I'm enjoying it, esp since this is probably our last. It has been a smooth pregnancy all things considered. The boys are doing great and we are looking forward to spring. So, I know I'm blessed and I'm just praying that God takes care of the things I can't control.
