LOTS OF GAS

I'm on my cycle day 24 and for about 5 days now I've been super gassy and I mean like I'm farting every couple minutes. The first 2 days I was super nauseas and had diarrhoea about 5 times a day. At first I thought I had a stomach bug but now 5 days in I still have slight nausea and I'm super gassy. I also just have been super glowy like I just have this butterfly feeling in my gut that I'm pregnant. But I don't wanna get my hopes up. I'm due for AF in 6 days. Has gas been anyone's symptom before?? SO and I have had sex almost everyday this month
