I took a pregnancy test at 8 days late after my period, but had a negative pregnancy test. I'm not 10 days late and still nothing. Normally I'd get a bad day with mood swings two days before. I had everything I usually do before having my period such as sore breasts, major cramps and they all went and still didn't get my period. When should I test again? I've had a 28 day cycle for roughly a year and very rarely my period would come late (only up to 3 days) I haven't had any contraception, I'm neither stressed or depressed, I haven't had a change in lifestyle or I haven't gained or lost a lot of weight. Has anyone experienced this and what was the result of the test?
