freaking out

So I take my pills RELIGIOUSLY. Like everyday same time. Let me get that out of the way. My SO and I had sex multiple times bout a month ago. Used ancondom. He came in me but in the condom every time. I'm on day 3 of my placebo pills and I've hardly been cramping. Been bloated and gassy . My period usually starts tommorow and I'm freaking out. Do you think I'll start or am I worrying for nothing?
