From the POV of someone who's been trying for 2.5 years and is now classified as infertile ... I really wish I hadn't been so blase about answering people's nosey questions about whether or not we were TTC. We used to just laughingly brush it off before we started TTC, but when we started trying, I'd answer, "Well, we're not really TRYING, but we're not NOT trying, if you know what I mean (nudge nudge, wink wink)! As in, I was off the pill but we weren't charting, hanging upside down etc. I was convinced we'd be pregnant immediately. I never even dreamed that we wouldn't be able to conceive. Now, everyone probably realises we're having trouble, and I feel embarassed about ever having discussed something so personal with anyone who asked (my old boss, my workmates, aunts, cousins, etc, oh God, I'm cringing as I type this!).
Really, unless they're very close to you, what right does anyone have to ask/pressure you about your reproduction?? I wish I had just told people (politely and with good humour) that it was actually none of their business. As in, "Hey, I don't ask you about your sex life!" or "I have my hands full enough looking after my dogs!"
I might have still told my mum and sisters, but with strict instructions that it was between us only.
I don't want to scare you - and the odds are on your side that your fertility is fine - but in hindsight, this is what I wish I had done.
