Possibly pregnant?

According to glow I was supposed to start my period yesterday and I always always always have started the day glow predicts. Well 2 days ago I had very light spotting yesterday had slippery like cm with a very light brownish tint took test came back negative this morning I've got nothing granted I've only gone to the bathroom once so far but could I be pregnant finally after 7 months of trying? I have some cramping but it seems more like gassy cramps not AF cramps breasts hurt BAD, I feel more tired than usual, acne, weird dreams, a little sensitive to smells but these are all symptoms I have when its AF time besides the sensitivity to smells. Please pray for us that we are pregnant this month!!! 😃😃😃
