Trying so hard ?

My partner and I decided a couple of months ago we would start trying for a baby and its been month after months with bfn, I've been trying old wive tales, pre seed and logging my stuff everyday but when I talk to my partner about my fertil days and making sure to have sex he acts like he doesn't care and says we will figure it out.... I feel so alone and like I'm the only one trying..... I feel like I shouldnt try so hard if he isn't gonna put his half in there it takes two to tango but I feel alone...
