Crypto scare?

I took on this gecko and kept her in a tub in my room to monitor. I didn’t have litterally anywhere I could quarantine her so I kept her in my room but tried not to cross contaminate or anything. But Im scared she may have crypto or something and I’ve infected my whole collection. they gave me some background on her, they’ve had her 2 years and kept her in a subpar enclosure. And apparently bought her from a private breeder. She has 0 symptoms of crypto and I was able to move her out my room about 2 weeks ago (I couldn’t before because my roommates wouldn’t allow) she’s been healthy for about a month. I have contamination ocd and it’s freaking me out super badly I’ve accidentally made a massive mistake in my collection. If seems very irrational because she’s never had any symptoms of crypto and she’s over 1-2 years old but she could be asymptomatic. I’m not planning on keeping her I just offered to keep her until I can personally rehome her to someone more experienced then herself. I’m just looking for peace of mind/opinions if anyone believes she might have crypto.
