You can definitely still get pregnant. I'm 45 and 11.5 weeks pregnant. However, at 17 days late I would think if you were pregnant you'd be testing postive by now. At 4 weeks, 6 days I had my hcg tested and it was already 18,762 by then. At 6 weeks, I saw baby and heartbeat on scan.
If you think you are pregnant, then have doctor do a blood test and that should let you know for sure; however, like I said, by 6 weeks I'd think surely you'd be positive on a urine test.
Though i am much younger than you & have no advice about menopause.. this is my second pregnancy so i have a little experience. With my daughter my urine came back positive immediately & i instantly felt pregnant way before my missed period. I think my positive ept was 6 days before my missed period. This time has been completely different! I didn't feel pregnant, though i had very subtle signs i chalked them up to something else. I tested 2 days before my period was due & got a negative. Missed my period & the next day tested again with a negative. I was like a week late before i got a positive test. So every pregnancy truly is different. You could still be pregnant, don't give up hope if that's what you're wanting.
