do you normally have a regular period every month?
well unlikely this is the endometriosis causing this
and with a negative pregnancy test and given you are 44, more than likely this is just perimenopause and not a pregnancy
Other reasons for not having a period and not being pregnant could be a thyroid condition which is easily checked with a TSH thyroid blood test
If you have more questions, please ask
I am here to help you
well if you do a second test and the second test from a GOOD company is still zero - and given you are 44, then very likely you are Not pregnant
I wish you well

Hello - are you there?
