This is a really tough question that only you can answer. You will see on here some women who have gone through years and years of fertility treatments and are pregnancy or holding their little miracles in their arms and some women who are still trying and waiting for their forever miracle. If you decide to continue on your assisted fertility treatment you will find so much incredible support on here.
Best of luck with your decision and will be praying for a BFP for you in the very near future.
