Please help!

Can anyone help, we've been trying for around 6 months now I'm two days late I took a test on the day my AF was due and negative and again today and negative. I've had tests done that show I have ovulated and my lining of the womb is thick which could be due to early preg or about to have my period. My boobs are usually so sore a few days befour my period and nothing ATM and I have a lot of Cm ATM sorry for tmi. Any advice?
