So let me give you ladies a lil background before my question. Im 23 and so is my husband. We have been together for 4 1/2 years. We have a 2 yr old, who will be 3 on dec.27. So my husband and i have wanted another child since we brought home our son. Last year in june i donated my eggs to a friend and she had a succesful pregnancy up until 19 weeks when she had pre-term labor. There was nothing the dr. could do to save the baby. She had a very hard time with the loss, so i offered to do a surrogacy. We did 2 attempts and nothing so she gave up faith. Back to me, i stopped taking BC (pills) on august 14 and me and my husband have been TTC since which isnt long. On glow it says my fertile days are from 9/28-10/4, now here is my question what days are best to BD ?
