4 cycles
1st 1 egg
2nd 2eggs
3rd 2 eggs
Today was 4th 2 eggs….. so embryos yet.
I’m gutted. This 4th cycle I have 4-6 follicles on scan. And just woke up to 2 follicles retrieved. When do I stop?! My specialist changes meds every time. I’m on coq10, folate, omega 3, vitamin d, zinc. I have one child that we fell pregnant naturally with. I can’t keep continuing like this 😞 Should I get a second opinion?
