I forgot to start my new pack of pills after a 7 day break and ended up missing five pills! Once I had realised I took the pills as normal until the pack had ended. During the that time I began to "feel" pregnant, cramping in lower abdomen, lower back aches, slight headaches, and infrequent feelings of nausea.I took 2 sainsburys own brand preg tests (-/+) and straight away (within the the frame) I noticed a very thin blue line which made up the plus sign. The line was very thin and slightly off centre. A few days went by and I took a another test, this time a different brand, it was negative.I know some tests have different levels of detection, imso I decided to take a sainsburys test again and I got the same result as I had initially, a very thin, blue, off centre line. That was about 2 weeks ago. I had heard that blue tests are not always reliable, so this put a doubt in my mind so took another test, this said negative. Still feel pregnant. By this time I had finished taking my pills and was waiting for period. I had what I thought was my period but it was not as it usually is. The blood was brown, some small clots. I had a very small amount of red blood, hardly anything, mostly brown. Took another preg test, said negative! I've waited a few days now and noticed I have colostreum.I am still cramping, have lower back ache,and my tummy looks bloated.The cramping and back ache is more often and more noticeable than when i'm due for a period. Took another sainsburys preg test, same thing happened, thin blue off centre line! Took different brand test, negative! I am so confused, can someone please give me some advice. Thanks
