Oh yeah, some swelling is normal due to water retention. Plus, with you being in your 2nd week, I wouldn't see having gyno ALREADY. It all depends on how sensitive you are to AAS. Me personally, I don't really need to take any type of anti E while on cycle untill around the 10-12 week, and by then, I am just starting my pre-PCT program.
You should be alright, just keep an eye on it and see what happens.
