I am currently taking birth control. I missed one a pill during my first week and took plan B (within 24 hours after sex) as a result of having sex that same day. Everything has been normal for the rest of the days. I am currently on my sugar pill week and I am on a very strong 28-day cycle. This means that I always start my period on Thursday. I took an early pregnancy test today (Monday) in the morning. I believe I messed up because I got a totally blue circle with a control line but no lines in the circle. I also believe I got too much urine on the test that morning and read that it was a faulty test. I took 3 other tests. Two being 88 cent tests from Walmart, negative and the other blue dye test from equate early response. That test, I got a line that could only be seen held up to the light and angled a certain way, it had no color to it and was off-centered. I also set that one down for too long as I was performing the other tests. It could not be photographed. I took the test apart and struggled to find it, but eventually found a grayish line towards the end of the strip. This was past the ten-minute mark on the test. I have no symptoms of pregnancy but, I am still greatly worried. I am technically not late on my period either as it should arrive this Thursday.
