peri menopause symptom or cyst??

[Andcake]

...this is the last thing I need this week as I have lots of work things on...but since Saturday I have had an ache on my left side - maybe around the ovary area...my periods are erratic since the birth of ds but to be fair I'm 42 and was diagnosed with low ovarian reserve at 35 and told I had very few eggs left...so lets say menopause is possibly on the cards. It was a miracle i had ds

Last night I had to take ibuprofen to sleep... is it a cysts maybe... my last period was 4 weeks ago but I haven't seen any signs of ovulation (and usually I do 2 weeks before i af shows) and cycles vary from 15 to 90 days...
ideas welcome

I once had the most painful cyst ever. Turned out to be the cyst that starts with a pregnancy- now 17 and painful in other ways! Even with a low reserve you never know. Might be worth checking out?

That has crossed my mind a few times - I am dithering with doing a test - but I've had so many negative tests in my life they just break my heart. I don't have any other symptoms like i've had before - 4 pregnancies - 1 child.
