I’ve always had normal on time periods my entire life and they are always heavy at first then get lighter. I’m 34 now and for first time I didn’t get my period on time but I have feeling like I’m on period expect I only seen brown blood when wiping nothing else coming out is this spotting? I’ve never had this problem before and now I’m freaking out and I definitely ain’t pregnant. I have been stressed since last period and I’m worried it has to do with age to. What do you think is wrong is it serious?
