Hi- I am five days past when my last period was due. I am usually regular and track everything on my phone app. The last time I was irregular was in Oct 2014 when I believe I had a biochemical miscarriage. I tested negative on two home tests and then positive on blood exam at doctors, later having my period come that day. I understand I could be late because of stress this time, but I'm more unclear of why the past two weeks and now again more I've had clear watery discharge. Its not similar to my ovulation cm...it completely resembled water and is not sticky or any color. no smell. I was tested two weeks ago for any and all stds and had my hormones checked. Doctor has not called to say anything was abnormal. This cm is new for me. I am fearful of being pregnant as I did have un-protected sex this past month and dueing ovulation. Want to know if period doesnt come and I test negative if I should be worried for anything else?
