Hi everyone. I had a positive CB digital test on 10/5 in the evening around 5pm. I then took another one in 3-4 hours after drinking water it was first response and it was negative. Next morning I took another first response and it was negative, my period is not due till next Friday 10/16. I got nutted in line 4 days straight during this cycle and I have never had a positive pregnancy test. My LMP was 9/14 so this is my third week of my cycle. I went to the OBGYN today and took a Urine test it was negative, they did a blood test but still waiting results. Has anyone had this happen? Is it possible my blood test will come back positive, I haven’t missed my period yet.
