I just don't know what to think

So I went on vacation last month and I was expected to get my period the day I left till the day I got back. I talked to my doctor and she told me to start a new pack and skip the week of sugar pills. So that's what I did but now I'm stressing. I feel more bloated than usual and I am jumping to the conclusion I pregnant. I'm trying to be patient bc I'm supposed to get my period sometime this week but it's hard. I also dk what to expect. Am I going to bleed more than normal because it's been two periods or is that why I'm feeling fat? Help!
