Seriously driving myself mad, exactly 1 week late today, normal cycle is 28 days, did a First response test on monday evening which was Bfn, sore heavy boobs, ultra oily skin, tired, very emotional, bunged up nose, lower back pain, achey stomach, bloated I could go on, is ir worth doing another test? Under the impression the 1st response is most accurate but due to amount of googling I've done, I'm not really sure what to think!
