Going all the way back to the OP, my MIL was like that for awhile (still is towards SIL's hubby).
DH was on the phone with his mom one night, and out of nowhere "Is she pregnant yet? Don't you know how to do that?"
Cue his reply of "We're still practicing"
She kept that up for over 2 years, and several months after she finally stopped, we announced that we were expecting. SIL's hubby is still getting harassed about it, but not as often, I think due to (A) she does have a grandbaby on the way and (B) SIL is having some major health issues that would make being pregnant a very bad idea for now.
For more recent topics...a few weeks ago I had a pregnant (stray) cat crawl into my pregnant lap for cuddles when she went into labor. She did decide to eventually move off of me & my front porch before any of the kittens arrived though.
I seem to attract cats that want to cuddle when I have cramps. My Princess-kitty always did, and several months after she passed, we got an older male cat, that prefers my stomach for a bed. Granted, after we got him, I only had my 'time' once, we'd had him for 6 weeks when I turned up pregnant. So now he cuddles next to me, and looks offended when he gets kicked by my tummy
