Egg sharing

So me and my partner have been ttc for 2 years. In my area they are offering free ivf if you donate one of your eggs to someone who doesn’t have any. I’m in two minds because I’m so desperate for a baby and I know the struggle and it would make me so incredibly happy to help someone with their journey to motherhood. On the other side it would be so weird knowing that I am technically a mother to someone else’s baby! My partner is very supportive and has told me it’s completely my choice! If anyone has ever done this or has an opinion on the matter or can give any advice please comment below! Thank you
