Your cycles can change as you age. You may not be ovulating when you think you are. Have you tried charting? If you haven't already, look for a book called Taking Control of your Fertility.
Also, try not to stress about it yet. That may be part of the issue.
you should talk to you OB Gen, if you're 35 and tried for more than 6 months you don't want to wait any more. I believe first thing they would do is give you a pill to help you ovulate, eg Clomid.
I was in the same boat. Got pregnant with my 1st two kids, no problem. Got off the pill in January of this year and couldn't understand why I wasn't getting pregnant. I decided to track my ovulation using a fertility tracker app and found out I was on a 31 day cycle and not 28 days as I thought. It took me 1 month once I fgured out my correct ovulation time. Im now 5 weeks. Give it a try! GOOD LUCK!
Maybe ur thinking about it too much I was same it took me 7 month to get pregnant n then after taking tests all time Everytime I just gave up n took my mind off it then boom we found out I was pregnant and try taking seven seas pregnancy vitamins it's got floric acid in them and all other vitamins which help with getting pregnant sometimes there's just something missing in ur body I took them after 3 month then got pregnant 4 month after I think it was down to taking them n keeping my mind of it
My husband and I wanted to try when we got married, after a year of recurring vaginal fissures, we decided to really try. After trying for 5 months, we went to a fertility clinic for a consult. We tried for another 5 months, then had another consult. We decided we were going to start fertility drugs in November of this year and try artificial insemination. I ended up pregnant at the end of July. I honestly thought I was out for the month.
