So I've done a pregnancy test and its come back negative and I was due on Sunday my periods are every 21 days so for me this is late me and my partner are trying so it's not a a shock to me however I am on warfarin which is very dangerous for the baby and could kill it and I'll miss carry. I spoke to nurse yesterday who spoke to a doctor and they wouldn't do anything about me being late and told me to wait because if they stop the blood thinners I could get another bloodclot but if im pregnant and carry on taken them I could kill the baby as I'm meant to go on to injections when I'm pregnant. I am constantly tired have backache feeling sicky not to mention horrendous headaches and going toilet a lot. What do you ladies think? Xx
