Going insane

Sarah

I’m three days away from getting my period I’ve felt offish for around a week now I’m 21 and ttc for a year now I’ve had 2 miscarriages very early on ive just had been feeling different than usual I took a clear blue test today (not digital) and it came back negative I know early pregnancy can sometimes mirror pre menstrual symptoms my real question here is what are everyone’s views/experiences with testing before you period?
