My last period was may 16th and i was due for my next one on June 13th..it is now June 22 and i started spotting yesterday. It hasnt picked up any and is kinda pinkish. I have been feeling really nauseous the last 3 days as well and my appitite has increased quit a bit. I took a hpt 1 week after i was late and it was negative. Should i wait and take another test or could it just be my period?
