Typically pigs are pregnant for 114 days (3 months + 3 weeks + 3 days). It is normal sometimes for a pig to not even look pregnant up to 3-4 weeks before she is due. Normal labor signs of contractions, vocalizing, sometimes more aggression/wanting to be alone and vaginal discharge. Unfortunately I cannot tell how far a long a pig is by pictures. It is uncommon for pigs to have complications with there deliveries. You could always have a vet comes out to help determine how far a long they are. Hope that helps

    Hello, Pregnancy in pigs is generally about 114 days give or take 2 days. If Penelope did become pregnant by this boar, then you can run a series of tests to measure hormones however these may be expensive. Alternatively, you can obtain an ultrasound to check for pregnancy. Hope this helps and best of luck.
