Maybe I should let it go gray!

I started getting gray hair in my early 20's. I have naturally dark brown hair (I think) and it is easy to see the wiry, gray hair mingled with my dark tresses. I would color it from time to time but it was not too bad. That all changed in 2005 when I developed large gray chunks and could no longer deny that I must color them, and often. I have heard that stress causes gray hair and I did not believe it, until 2005. That was the year that we had lost Abbie (our daughter, lost through a failed adoption). In the 2 weeks preparing to let her go my hair became unrecognizable. Dying was barely covering it all, so I opted for highlights. At least then the gray hairs look like a "highlighted" strand of hair instead.

Now this baby is causing me gray hair and it has only been 6 weeks since we learned of his existence. I can't imagine what the next 8 months will be like!! Maybe I should just give up and go au natural! Why am I stressing, you ask? Because I woke up spotting again this morning. Previously it was very minor and light pink. This time it was darker red and very noticeable. I noticed it at 7 am and by 9 am it was over. But it was enough to make my heart stop. I love this little one already and it terrifies me of losing him. I am resting today and taking it easy. If it continues I will call my doctor. If he keeps this up, though, my hair may turn so gray that when he is born people are going to think that I am his grandmother, not his mother!!
