Hi all im pretty new to this, I have 3 different trackers on my phone, Me and my husband have been trying for a baby since june, We have 2 girls already aged 9 and 6, i am currently 17 days late, all my home test are negative, (clear blue, first response and cheaps ones) i also had a blood test done when i was 9 days late also negative, I'm a bit stumped as to what could be going on, I have been suffering from nausea but have only been sick twice and ive had twinges, Not movement.. i have the doctor again on the 29th december which is the day i would be due to start my period again, last period was the 3rd of november and im always on time. Any advice given would be greatly appreciated.. Thanks
