Ok so I was due on my period on the 21st of June i started having Brown bleeding light for 1 day then of then on again for another two days on the 16th of June. My period didnt come on the 21st like it should have only the spotting. So my next period would be the 14th of July. So today is the 1st I started with Brown bleeding light again yesterday morning then stopped and again today . Am I pregnant or is the something wrong by the way I had a negative pregnany test
