Could I be pregnant ?

I’m 45 and last year I got pregnant but unfortunately lost our little one at 17 weeks, my periods then became irregular so I was presuming peri menopausal, then all of a sudden from August my periods restarted. Well they’ve been a lot heavier than normal until my last one two weeks ago. I was prepared for a heavy period but I only had spotting for a couple of days , I’m extremely tired all the time, my boobs are itchy and tingle but not sore, I’ve been feeling sick but i don’t know if I’m confusing my symptoms with menopause or it’s in my head.

I did do a test but it’s very very faint ( obviously can’t show it as dried out now) .

In March I’d had an internal scan which showed slight thinning of my womb but plenty of eggs.

My fiancé and I have been trying for two years and I’m so worried my times up with my age.
