It can be very stressful which we all know does not help us getting pregnant. You need to look at the positives you got 4 eggs, and 2 in planted and possible 2 more if you are not already pregnant. Keep positive, don't worry so much and take it easy on both of you.
Congratulations for getting thru your first IVF cycle!! Daunting and rollercoaster are good words used to describe the process. I underwent several cycles. If I can help you in any way please message me. I would be happy to share what I experienced if it helped you in any way. Visualize those two beauties grow beautifuly and being placed in your uterus on transfer day.
I will be thinking about you.
Best of luck!
