I’m at a loss....

They say when you stop trying it will happen. well I don’t know what to do anymore.....I can’t just “stop trying” because my husband is HIV positive and we can only have unprotected sex during my fertile week as I don’t want to contract HIV. we’ve been trying for so long I just don’t know what to do anymore. people think TTC is hard, imagine my situation, it’s 10 times harder. 😔
