Testing too early

Emma

I had chemical pregnancy last month! My period is due in 4 days! I had a little spotting on Sunday last week,it was literally a bit of pinky orange when I went to toilet twice then nothing ! I’ve had twinges and pulling sensation and mild back ache all week,did a Sainsbury’s test this morning but negative although it says you can test 4 days before period is due!! Wish I had more patience.
