Worried.....

Over the summer I found out I was pregnant. When we weren't trying. And don't judge but the night before I got a positive test we went with friends to a bar.  I would never knowingly consume alcohol if I knew I was pregnant. But miscarried about 2 weeks after I found out at roughly 6 weeks. I work a very physical job and I'm worried that could have affected my pregnancy. Since then I have gotten married (in October) and my husband and I have been ttc. According to glow we did the deed when I ovulated. I'm supposed 11 dpo. And my breasts are sore (that was how I found out over the summer) but the tests I have taken have been negative. I just worry that my job and riding my horses could cause the same thing to happen. So how many days past did y'all get positives ?
