Really worried I’m going through the menopause:(

I’m 33 years old and have 3 children, I got with my new partner about a year and a half ago and decided after 6 months that now would be the time to start ttc as age isn’t on my side. My partner is 26 years old and has no children of his own. It’s now been a year of ttc and no luck at all. I’ve been using opk’s for the last 4 months and nothing has happened. The last months I have been constantly getting positive opk’s and negative hpt’s so I could rule out pregnancy being the cause of them. I went 2-3 days with negative opk’s through my whole cycle. I’m now on cd26 and the last few days my opk’s have been stronger and stronger every time I test. Has anyone got any insight into menopause and if it can be the reason for positive opk’s and prolonged lh surges? I’m so worried that I missed my opportunity and will not be able to have anymore children :( x
