I’m 9 days late on my period and this has never happened before so it isn’t normal but I took a pregnancy test 3 days after my missed period and it was negative. I’ve been having horrible back pain and sore breasts which aren’t usually as bad on my period. I also have been having cramps the past week and usually I have them the day before I start my period. I’m planning on taking another test in the morning but if it is negative should I just not worry about it anymore ? Or could I still be getting negative tests and be pregnant ? Also my cycles normally 30 days long but it’s obviously past that and I’ve had intercourse several times the past month.
