Hello has anyone experienced something similar? I’ve been testing for a whole week now but every test comes back negative however when I test with an opk it comes back positive, the test line is a lot darker than the control line and it’s been the same for just over a week. I’ve been testing this cycle and I had a positive on the 2&3rd of this month and they were negative up until 14th where they remained positive till this day. my periods are very irregular but I am on cycle day 44 but I’ve never got this far before.. my period tracker app says I should be due on the 16th so I’m assuming I’d class this as being late?
