So I’m at the end of my period and Let’s just say this cycle was not severe but bad than what it was last time, not sure if this is period related or not but I’ve been getting this pulse feeling that comes and goes it’s like at my right side/ stomach and it doesn’t hurt it just is a quick pulse feeling then it goes away and comes back. Sometimes it lasts a few seconds. Not sure what causes this but does anyone else have this issue sometimes or am i crazy
