Freaking out!!!

Gas and bloating pain today, no major cramps, but when I went to the bathroom just now, there was spotting! I'm 5 weeks! Please tell me it's not a m/c!! No one who's with me tonight even know that I'm pregnant! I don't know what to do!! I was wearing jeans just now that we're too right on my stomach is it maybe cause of that??! God I'm scared!!
