It depends on age as well. I think if you're over 35, then they say to go to GP after 6 months.
I’m in the United States and I’m 28 turning 29 this year. My husband and I have been trying for 6 months. At this point I regret waiting like the doctor recommended. They recommended a year half after my son was born. I wanted my kids close together to wait that long to see a doctor I will never get that.
Depends on age. Under 35, 12 months. Over 35, 6months
Idk what tracking you're doing if ur doing any but BBT is a great way to track ovulation. Also if ur breastfeeding still you may or may not be ovulating. Go back to your obgyb
If you are in the U.K. you cannot be referred to fertility until you have been actively trying for 12 months, you can always go to the gp before to start tests but a fertility nhs will not see you until after 12 months x
