problems with getting pregnant

this year my period has been irregular lately, my husband and I have been trying since October. with every period that comes I get more and more depressed because my cycle is completely off. so i went to stay with my mom for 2 weeks I go home Sunday I needed to get out of the depression and keep my mind busy. I got a pic msg yesterday he got ovulation test and preseed. we never used that before and caught me off guard. He may not bring me flowers but the fact that he went on to buy that means more to me.
