I'm a little confused, i was due on Tuesday... Nothing, sometimes a day or so either way on my estimated start date so not too worried. Thursday... Still nothing but felt terrible, hot flushes, light headed, nausea... Thought that's it I'll definitely come on...Little spotting but nothing else. Friday and Saturday no spotting but both mornings felt nausea and extremely run down. Today a little cramp earlier and spotting but nothing since... I'll probably come on as I'm writing this haha. Any ideas? I did a test Wed but negative. I've been feeling a little down and delicate lately, could that mess my cycle up?
