I have tested every day since friday with an early test thats meant to detect from 15mIU, only todays test was first morning. Today (sunday) its been 30 days since start of last period (was on 4th of March). Usually im between 30-33 days. DTD 19th, 20th and 21st. Every test has been negative and im thinking this month isnt the month, I only have one test left and im trying to hold off testing because I dont want to have to go buy more and look silly. Any ideas?
