missed my chance??

Fiona
During my fertile week I took ovulation tests every day. On the 3 Dec I had just one line, BD anyway. On the 4 Dec I had two lines but husband was away so no BD. 5th Dec he was back but I tested and it was only one line again but we BD anyway. Did I miss my chance by missing my surge? Not feeling hopeful :( bn TTC for 5months..
