I agree, don't be sad...celebrate the new little life you have inside you!
Given all the phsycial issues you have had I understand fears. Try to let the past issues not be a part of your thinking now. Often once the body deals with HPV cell issues they don't return. Pregnancy can bring on a flare up but I think this might be more with warts. That may be exactly why yours came back so strong. Once you give birth and your body goes back to normal you should see a decline in warts again. Basically your immune system is supressed just to allow the pregnancy and your hormones are out of wack. That also leads to the mood swings and being sad. There are many options for treatments with any HPV issues so try to allow yourself to only focus on the good of your life and future!
Don't be sad! I'm in your boat, only I never had gential warts from HPV...they only flared up when I got pregnant. I'm hearing more and more how common this is. You can get trichloric acid treatments when pregnant and this poses no threat to baby :) Also, my doc said that he has never seen a baby affected by HPV. Worst case-is that you will have to deliver via C-section, but he said this is rare as well. It stinks that Pregnancy can accelerate HPV and genital warts, but the biggest thing you can do is to communicate with your doctors about every concern you may have. Eat healthy, don't smoke, take your pre-natals, and you should be fine! Hang in there, girl! And best wishes to you and baby!
