Feelings sad

So my husbands daughter from this girl he slept with was born on Sunday ( he slept with her before my time) yes I knew she was there before we started dating and before we got married. We're ttc.. this would be my second period after my iud removal. I have almost every single pregnancy symptom.. every test is negative. I took a hpt and got a bfn. I'm hearts broken. And when I told him how I feel .. basically saying it hurts that my body fails but he gets some whore pregnant ( they were never dating just a fuck buddy).. he took it the wrong way like I blamed him. I didn't. I feel like I failed as a woman and as a wife :( I'm bout to drink a whole bottle of wine in a bath and ball. Hopefully I can sleep tonight.
