I am worried that my female SH Syrian ( Bie ) is pregnant. I found my male LH Syrian ( Sumo ) was in Bie's cage for maybe whole day ( I left at 8am and back at 8pm, I'm not sure he is been there for how long ). Its on 7 December. And few days ago I found there is an nipple line ( or maybe its not, photo attached ).
Can it be knows of she is pregnant or not by photo only?
Also, it it possible if they were mating during day time?
1st is when I placed her in her sand cage while I am cleaning her cage

2nd photo is her nipple line, I think?
