Absolutely it’s still possible to conceive at that age!
I’m 38 and 18 weeks pregnant, will be 39 when this baby is born.
I suffered 4 miscarriages while ttc.
I was told it was likely down to my age and old eggs but equally that it only takes that one healthy egg!
I had various tests done and scans etc with a fertility consultant and all was perfect, as was my partners semen analysis.
I took 200mg ubiqinol a day (the more easily absorbent form of coq10), along with a high dose folic acid and a high dose of vitamin d.
After my fourth miscarriage I did a LOT of research into taking a low dose aspirin to help and vowed that with nothing to lose I would try it next time.
I then took 150mg a day from 1dpo and here I am. My midwife and consultant have both said that had I not been taking it they would have put me on it anyway! It’s shown to help many women who have suffered multiple losses, and there are many threads on here where it’s helped.
Good luck! I was so close to giving up when this pregnancy happened.
