Have anybody been late for their period four to five days and took a test but it came out negative but really was pregnant later down the line because I'm freaking out I haven't got my period for July and I thought I was pregnant I have gotten many early symptoms far as my nipples being sore my breast being sore to touch with green veins going around them I have pressure and stretching feeling in my uterus with cramps I've been nausea and certain smells been more upfront but I keep getting negative pregnancy tests my sister thinks it all in my head and that not pregnant because she said anytime she missed her period and took a test it was always positive and if mines came out negative then I'm not pregnant probably just delayed period can anybody make since of this for me and help me?
