So I'm currently 6 days late. I did a test earlier this week (? Monday/ Tuesday) and it was negative but still no period. Tested again this morning first thing. Negative. Now due to shifts and illness we only dtd on 13th and 22nd of this month. I had a 28 day cycle before going on the pill but August was the first since December that out was back to 28 days. Before that it was 77 ...65.....55..... etc.
So. .. reason for this? Are the tests wrong?
