doeling not going in heat - somehow pregnant?

[Bcvagoats]

Hi everyone, I have a 6 mo minimancha doeling that has not shown any signs of going into heat yet, though her same-aged half sister is having loud, regular heats. Should I be worried she is somehow pregnant, or should I chalk it up t her being a later bloomer than the other doeling? For background, I have had her almost 2 months. She was in with wethers and other does where I got her from, but not sure how soon wethers were put back in with the does/doelings after castration or how long bucklings were with doelings before castration (though she came from a responsible breeder). Here she is with the other doeling and a wether. My wether was banded before I got him, and it doesn’t feel as if a testicle was missed down there. There’s no way she could’ve been exposed to a buck here. Where I got her, there was a buck on the property but he was house separately and out of sight. I attached some pics in case helpful. Am I overworrying?

not sure, we have a couple mini-manchas and they cycle every month.

I'll tag @Southern by choice and @Goat Whisperer as they have mini-manchas

I don’t see any reason to assume she’s pregnant, but you could send some blood to a lab and find out.
Most of my does stil aren’t cycling for the year yet. Also, occasionally you will get a doe with an extremely sneaky heat.

I agree with Rosti, Send blood out to Bio-pryn it is less than $4.
We are sending out 20 vials tomorrow. We know some are open but want to verify.
