Are there any mums here in their 40's

After several (10) very faint positive, and only a couple of negative tests, I'm left confused and wondering if I really am, have had a few pg symptoms, and what appeared to be implantation bleeding a week before af was due..

I recently read that woman in perimenopause/menopause produce higher levels of hcg..

My periods have been a bit off in their cycle, particularly in the last 7-8 months ..

I'm frightened that I've gotten my hopes up and what I thought might have been implantation was actually just an early period and not implantation..
