My boyfriend just crushed my heart 😢

I'm on CD 25 and waiting on my dr to tell me what the next step is I had my blood work done on the 23th. Last night my boyfriend gave me the news that he might have an STD!!!! He blames me for it but I've been faithful in our relationship and have been trying to have a baby and now he tells me this. I'm so broken and hurt I was so excited to be going through this journey with Clomid hoping that I would be pregnant and now its taken a turn for the worst. Sorry I just needed to vent and hopefully get some advice I've been crying since he told me.
