Could this be an issue ?

So a few months ago I had a major die-off of fish, thankfully I have since been able to recover, whatever sickness they had is thankfully gone now. Problem is that one of the fish I had (A grey mickey mouse platy) was pregnant at the time. I could tell this for a few reasons, 1: I witnessed the whole "thing" where the male fish twists his body, 2: Stomach got a lot rounder, 3: She was hiding a lot in dark and "quiet" places in the tank. Either way, it's been a few months since then and she never gave birth, I assume from all the stress that happened then that the Fry probably died inside of her. She still act's like she was when she was pregnant, however. I wonder if it's possible that she still believes she is pregnant? and could this be a problem?

Pseudopregnancy is a real thing, but to me, it sounds more like your fish is exhibiting stress behaviors rather than false pregnancy. Stress can come from a multitude of things; poor water quality, incompatible fish, sickness, etc. In order to determine what is affecting your fish, we will need to know a few things about your tank and fish. Could you please answer the following questions and get back to us?

What size tank is it?
What fish and/or invertebrates are in the tank?
Is the tank filtered? What's the temperature?
How often do you do water changes and how much do you remove?
How long has the tank been set up?

Once you answer these questions we can better assist you.

10 gallon tank,
2 fish, both platy,
Tank is filtered by a hang on back with a prefilter sponge,
Temperature is 78°F or around 26°C,
I do about a 20-30% water change at the end of every week.
The tank has been setup since March 2020.

Also forgot to mention, I also noticed a black spot thing develop inside her (since near her rear end, her body is not fully translucent, but you can see just a bit through her) when her stomach got bigger from the whole pregnant thing.
