I am now 9 days late on my af. First pee this morning was a BFN! :( I'm usually never this late. I'm usually at the most 3-5 days late. I have no signs of my af coming on. I recently starting dieting alittle by drinking meal replacement shakes for lunch and taking metabolism and energy vitamins. I've been drinking more water as well.  Could that be why I'm late? Or could that make it show bfn? Could I be pregnant and still to early to show? I've been going to bathroom more frequently and couple nights before bed felt nausea. Boobs are a tad sore but not much. I don't want to get my hopes up but it's making me ancy being this late! Hoping I haven't started by weekend and will test again and hopefully get a bfp! Advice please!
