Talk to your dr! There could be a problem with you, your husband, or both. There are many causes of infertility that can be treated. No use in speculating, make an appointment and get appropriate tests run so the best course of action can be taken.
Here's something I found. I haven't had regular cycles since my first was born. Diagnosed with polycystic ovarian syndrome. Im told its difficult to become pregnant with that. But my second and third child were both conceived when I went back to work at jobs that didn't allow for sitting. Lots of standing and moving. I would lose weight and get pregnant.
The doctors say I'm morbidly obese because of their stupid BMI chart yet before I got pregnant I was a size 16.
You can also buy ovulation tests from the dollar store which may help you predict when you ovulate.
Talk to your doc and start a fitness/healthier eating plan (if you have not already). I find that when you feel healthy, you think healthy, and more doors, including sometimes baby having, open up to you. Good luck!
i started trying when i got married at age of 26, after trying for an year consulted doctors who says i shld continue trying naturally as there seemed no issue, it was at 30 when i started fertility treatment and they diagnosed anti bodies issue with hubby and i conceived via ICSi when i was 31. i have daughter who is going to be six and i conveived now naturally which is surprise as i am 37now. bottom line is i dont think its the age factor that matters but seek fertility treatment i hope you will conceive with the such advance treatments available these days.
I think that is something only a dr can tell you. I am 35 I also have endometriosis, and didn't think I could still get pregnant. My endometriosis seemed to have gotten worse over the past 11years since my youngest was born. yet here I am. You are older than me, and only you know your body, talk to your dr,you never know what can happen. I hope the best for you.
