So every time I have sex we use condoms. I’ve been getting my periods every month. Sometimes my cycles are longer than others but it always shows up. Unless I skip a month every now and then. I just had my period September 14-19 it was heavy for 2-3 days and then brownish and less heavy for 3 days. Could I be pregnant? Or is there no way you’re pregnant if you have bleeding every month? I’ve been having spasms and twitches in my stomach for like 2 ish months and now they’re happening in my back, ribs, knee, and other places.. should I be worried???
