Crusty white nipples, cat further along than estimated?

[Semicrazycatlady99]

Hello! I’ll try keep this short. Our cat likely mated with a local tomcat while we were away on holiday (our neighbour was cat-sitting). From our estimate she would be around 5 weeks pregnant. Today I checked her nipples (as I do every other day) and there’s a white crust on every single nipple. Could she be further along? This is her first (and last) pregnancy.

Everything is possible. If she sneaked out or the tomcat managed to sneak in... but if she is at 9 weeks, you would see other signs too. Say felt kittens move.
