I have 2 adult female checkered garters, and a pair of red sided garters.
I couldn't find a checkered garters male to breed with, so I wanted to see if my red sided garter would maybe do something, surprisingly he did.

So, now this was in the beginning of December (have exact dates at home)

Now how do I know if she is gravid because I have my 2 adult females in 1 one enclosure, since they were toothpicks, but naturally I would need to split them if she is gravid and add in all the necessary goodies to make her comfortable etc...

behavior changes:

1. very agitated
2. tail wagging for nothing (slowly, not a rattle)
3. she is larger than the other
4. she is still eating
5. she coughed up some... slime stuff?! last night but that was my fault I was fixing their cage, and had to move them to do so.
6. sometimes it looks like she want's to climb out the cage, up the sides all over the cage... then suddenly stop, not moving for some time.
then slowly start moving around again.
7. I can't feel anything inside of her, there is long lumps but that could be because they were fed a few days before.
8. when I pick her up, her tail curls into a complete circle, and looking very uncomfortable, this is one of the signs of carpet pythons being gravid, so I'm just wondering if this could apply to them as well.

so... very confusing signs?!

Can someone please clear this up for me.
Thanks in advance, this is my first time attempting to breed this species in total I now have 6 garters, a pair of red sided garters, 2 adult female checkered, a young albino checkered female and a very young male, still a toothpick

Hope you can sort me out.
