Coq10? Experiences?

Have had 3 miscarriages in 10 months from 5 weeks to 10 weeks.

Had a follow up appointment with hospital yesterday who were unhelpful and said oh it could be egg quality so you should go for <a href="">ivf</a>- however my 10 week pregnancy we saw a heartbeat twice so I am sure it isn’t necessarily this and don’t want to just resort to <a href="">ivf</a> especially as I don’t quality on the nhs!

Has anyone taken these to improve egg quality? Experiences?
