It is normal for a pregnant guppie to have a reddish interior on her Travis spot
There will be a dark spot in front of the fishes anus (cloaca) in a pregnant (gravid) female livebearer. This spot is called the "Gravid Spot".
With a guppy you need to look at the gravid spot. This is a dark spot in the fish's belly. A large gravid spot indicates the fish is likely to be pregnant. You can tell how pregnant the fish is by how large the spot is. Sorry I have no experience with other species.
A girl can get pregnant any day if she's not using protection.
If you have a period than you are not pregnant
If your spotting one day, then get your period the next day, that would indicate that your are NOT pregnant...
it means that the earth will travel one spot and back to that same spot in 1 day
