1st timer with tropical fish

Hello! sorry if there is already a topic about this but I was hoping somebody would be able to give me some advice.

Ive recently (2 weeks ago actually!) set up a tropical fish tank and I think one of my Molly's may be pregnant.
I asked at the fish shop if she was pregnant and they said no because she didnt have a black spot on her or something like that? However she is very bloated.

I got 2 Molly; one just looks like a normal fish and chases the other (the fat one lol) around the tank. I bought a breeding tank today as she started hiding in the cave on her own away from all the other fish and she isnt really doing much. I have her in it at the moment but obviously dont want to leave her in it if she is not pregnant or not ready to have them yet.

How can I tell if she is pregnant? (and if so when she is going to have them) or what to do if she is ill (as laying around not doing much doesnt sound very good)

Any advice will be very welcomed!
Thank you

for starters, do you have a male and female together?

Can you post photos of both fish and list the tank conditions, including size, temp, water params for ammonia, nitrite, nitrate, and pH?

How much decoration is in the tank?

Mollys have a gestation period of about 30 days, and they can have 50+ fry each time. (yes, that's a lot of fish)
A male and female pair is not a good idea. Their favorite thing to do is breed. Any female coming from a store tank is likely to be pregnant, but there is no real way to say for sure how long til the fry are born.

If you only have a pair, the male only has that one female to chase non stop, and they are known to chase the females until they die from exhaustion.

Once we have more details about your tank situation and hopefully some clear pics of each fish, the tank, etc... we should be able to help further.

Those water params are very important, so please don't forget to include them!
