Wow, I actually am pregnant. I'm starting to believe it now. We saw a teeny, tiny smudge with a yolk sac and beating heart. We were using the offices crappier ultrasound machine (next week I'll get the good one) so our RE couldn't get an exact heart rate count. However, he said it's well over 100 and is super happy with progression so far. Obviously, I know things can still go wrong but for today, I'm pregnant and thrilled.
