Trying to conceive HELP!

I’m going on month 12 of trying to conceive. I was on the patch for a couple of weeks in that 12 month period. I recently visited my doc and they did fertility bloodwork. Everything came back normal but I’m confused as to why it’s taking so long for me to conceive. Is the problem with me or my husband. I do use OPKs and do get a LH surge . Any suggestions on what should be my next step in TTC?
