Is there still hope

Hi ladies. I am 34 almost 35 in May. My husband and I been actively trying to conceive for 6 months now.. I am 4 days late and have tested twice but both are negative tests. First I tested at 14 dpo (so I think) and today is 17 dpo according to the app. We did not use the ovulation kit test this time around as I think it put more stress and pressure and took the joy out of the baby dancing. I am usually 28-30 days at most I’ve never gone more than that. I don’t understand. Went to the doctor earlier this month and she said I shouldn’t be concerned as I have had two children 10,2 that it just takes time up to two years even.. I am getting really discouraged as that my body is saying I can’t have anymore kids. I am in tears and losing hope I will not get pregnant again. Any one have an idea or has experienced this or something similar😢💔
