Maybe a TMI post, but please read...

Okay so I am 37 weeks pregnant with my second. I never noticed this with my first.. But last night I noticed I had an ingrown hair in my pubic region... So I brought out a mirror to check it out. Wow. After not seeing that area very well, or at all for the past couple of months... Ugh. Is it normal for the skin to be a completely different shade? Like 5 or more shades darker than it ever was??!!! Even in the creases of my thighs down there it has completely darkened. I am so grossed out! I know for a fact it wasn't this bad after I had my first son, and I'm just worried (shallow, I know) that it won't go back to my normal skin color. Added anonymously because I am incredibly embarassed about this! Please tell me I'm not alone here :(
