It varies, its not an exact science! As l said before the only way to be sure is to wait 10 weeks from when she was definitely with a boar. If she starts to look a pregnant shape you could take her to your vet for an examination, but even that is not 100% reliable, sometimes, most times, you just have to wait. It can seem endless!I went to the pet store today to get a bale of hay and they are pretty certain that she shouldn't be pregnant but they couldn't give me a date that they separated the male so that's annoying. If she is pregnant will she gain normal weight until she starts showing she is pregnant ie pear shaped and then begin to gain more weight or will it be more gradual than that?
