I was due for my period today and just took one of those clearblue pregnancy tests, now im a little comfused because both the bubbles have got lines in them which means im not pregnant, but the bubble that says weather or not you are pregnant or not is a very light line compared to the small other one, are they meant to be like this ? Because the smaller one is quite dark blue but the other bubble where it tells you if your pregnant is a light blue ?
