AF whilst pregnant

Has anyone had a bleed in the early stages of their pregnancy which felt like a period? 
Stupid AF came VERY late (😡) for me. Was very dizzy for 2 weeks before and now it's got worse. I'm only on CD4 and the bleeding has subsided (also very unlike me!!) but am really, really dizzy still and nauseous. I am tired of testing and being disappointed - what do you all think? 😞 Even if you haven't bled, have you got any advice? My patience is wearing thin 😞😞😞
