Changed his mind ?!?!

Julie • Been with my husaband for 15years we have all boys . 12yr old , 6year old and finishing up the family we have a 2 year old.
So my husband and I had decided that we wanted to try for baby #3 . We both had gone back and forth if we wanted to try or not and last month decided we would  start trying , so first month down and not pregnant so I bought  OPK off Amazon and felt excited  that we were trying for our final baby. Well this morning he said we were done and that I should return the OPK, I'm confused I don't know if he is just messing with me to get me going ( he likes to do that) so I told him fine then there was no reason for us to shave sex anymore he laughed and kissed me goodbye as he left for work.. Now I'm so confused and I don't know how to handle this situation
