DTD...Fr or abstain question help please
I'm new here! I have been on IG for a few months. I have found a lot of information on this site helpful. I'm really conflicted on what is best for DTD. Can someone guide me to do FR or abstain....not sure what would be best for us. I will give a little back story as to why I'm conflicted. I'm 37 and DH is 35. We have 3 boys 14, 11, and 6. In 2004, a month before we conceived our middle son, DH found out he had testicular cancer and had one removed at the age of 23. His doctor said he needed chemo and that may make him unable to have kids in the future. His DR. advised us to freeze his sperm just in case. We had the clinic test his sperm to see if it was ok. The nurse joked that even with only one testicle his numbers on all tests were so good he could look at me and I would get pregnant. We decided to try to get pregnant before his chemo started. We DTD everyday for at least a week and got pregnant that month. Fast forward to 5 years past his chemo and we wanted to have another baby. Not knowing if we could get pregnant we tried anyway. We DTD everyday at least a week and I got pregnant with our 3rd son in 2 months. So it seems he still has super sperm and FR still gave us boys. Or maybe that wasn't FR enough. Now it has been 6 years since our last son was born and I wonder if FR will get us yet another boy. I had read on this site that abstain isn't good for men over 35. He turned 35 5 months ago so I'm not sure if he would be ok. Also I'm pretty sure we DTD through OV with all three so I feel like a cutoff might be better but again I just don't know. Please help me figure out what would be our best plan. Both our hearts pray for a little girl to complete our family. Thanks
