Fish Oil recommendation

Hi, I have been consuming fish oil by the brand of DHAextra purchase from my gynae. However, I discovered the recent batch of fish oil (manufactured as of July 2019) is very different from what I used to have. The capsules are much smaller and harder and I kinda feel uncomfortable eating it, not too sure if this batch is the same as I had before. Should I feedback to the clinic? On the other hand, do you have recommendation of other fish oil brand that is good to consume during pregnancy? Thanks
