Background: I'm 31, healthy, normal cycles (albeit very short - 23 days) and CD7 of the second month trying to conceive second baby. My period was a little late this month but I didn't get a positive pregnancy test. Period usually lasts for 4 days and tapers off gradually after a day or two of heavy bleeding.
I'm currently on day 7 of constant, bright red blood. It's not really heavy, but it just keeps on coming. Some small clots and a bit crampy, but nothing debilitating. I'm just feeling quite ill - my head hurts and it feels like I've got a hangover. When/do I need to worry/call a doctor? Could this have been a chemical pregnancy, despite never getting a bfp?
