No sign of pregnancy

I have a 1 year old kid. My husband and I are trying to have our 2nd baby. We have been trying since September but no luck. I was also nursing my baby at that time but now I have stopped nursing her. It has been over 2 weeks since I stopped. I heard nursing and such factors take time to be able to conceive another baby.. We have been having intercourse every 2-3 days since. I don’t know what to do. I get my periods regularly every month too and it’s strange. I am starting to lose hope.
