Here is the back story:
I normally have a regular 27 day cycle and according to my calendar I should have seen AF on 16/11. I tested using Boots own brand HPT on the first I AF had not arrived. Since then AF still has not arrived and I tested this morning, again with Boots HPT. I?ve used Boots own brand earlier this year and got a +ve and they say on the box it 99% accurate.
I am average weight and height and have no medical conditions (that I know of) that could cause me to miss a period. So, the question I?m asking is- can the test be wrong?
