You have nothing to be embarrassed about, I used to feel like you but then I thought its not my fault...why should I feel ashamed?!?!?! I pluck my chin and shave my upper lip infront of my hubby, its part of my condition and I can't help that its like that. While I was pregnant my hair improved alot, my acne got worse but the excess hair wasn't such a problem. But if it did come to you going into hospital you'd be able to take tweezers and a razor, so you'd be able to go into the bathroom and do what you need to.
I think you should be honest with your OH, you'd feel much better. I'm sure my hubby doesn't appreciate me tweezing my chin infront of him, but needs must and all that. I do what I have to do. xx
