I come of my period on the 6th May and on the 20th I had some discharge that looked like blood in but never happened again but on the 23rd May I started cramping and getting backaches and it carried on until the 30th and that’s when I decided to do a test and it come up with a very faint positive so I thought I’d give it a few day and then I tested on the 3rd June and come out negative but I’m 7 days late for my period and i have been having cramping, lower backaches, frequent weeing and also had a increase in bowel movements and still getting negative tests - I have only ever been 1 day late for my period in the past has this happened to anyone and they ended up with a positive at the end?

Last night (15th June) I was in bed and I got severe cramps on the left side of my stomach and up my back and I could barley move and now today (16th June) I still have cramps but not as intense and left boob is sore as well I really don’t understand what’s going on please someone help
