I'm no pig expert, but......have the two unbred gilts been in heat? Are they still coming back into heat every three weeks? If you are no longer seeing heat cycles, then they could already be pregnant even though you did not witness the mating.
It's never too late to start! I retired to homestead on the slopes of Mauna Loa, an active volcano. I relate snippets of my endeavor on my blog : www.kaufarmer.blogspot.com
