Background story:

I bought my first silver bengal queen Luna about a year ago (she is just over 2 years old). She was bought as an active registered girl so the owner knew I wanted a litter from her. Apparently she had one litter only and the kittens were not registered as she sold them to friends and family. She sold Luna as she no longer wanted to breed anymore.

Luna has been to a stud twice now, first time wasn't successful. She mated the stud several times but never got pregnant. So she went there a second time and they mated again. Its been 3 weeks since her mating and she has recently had morning sickness about 3 times. Her nipples have a slight pink hue to it but I'm just not sure if its pink enough! Her belly looks slightly enlarged but I know its too early to show.

Here's a pic, I would appreciate any advice...

In my opinion, you should not be trying to breed a cat until you understand and can recognize all the symptoms of a pregnant kitty. I've never owned a pregnant cat, so I couldn't begin to tell you. If your female registered as a pure bred bengal? Is the stud a pure bred and are you going to sell these potential kittens as purebreds? Are you willing to do the vet visits, vaccinations, spay and neuter of the potential kittens before they leave your home in order to preserve the breed? There is a lot that goes into this. We have breeders on this forum and it's a job for them. I hope if your female is pregnant and has a litter, you will then have her spayed. I know a litter of kittens is really adorable, but there are a lot of bengal kittens being born and they all need to find good homes.

Take her to the vet for an evaluation. The vet will be able to determine if she is pregnant or not.

Here are the pics... I will take more at the weekend to compare.

Your original post did not state you've previously bred cats. I'm guessing your real question is wanting to know if the mating took the second time. Time will tell if your girl is pregnant. It's difficult to tell anything from your pictures.
