Still trying and hoping

For the past 5 and a half years I was told by doctors that I couldnt get pregnant again after I had my daughter. Well, three months ago my husband and I found out I was pregnant when I went to the hospital for an overdose,( I struggle with suicidal depression for many years) we lost our baby due to my stupidity. A few weeks ago i took a test and it came out positive. Took two more and one was negative and the other was positive. I went to the doctor and they told me they would call me when they got my blood work back..we still havent heard anything a week later but I'm 5 days late so I'm hoping i didnt lose this baby....any ideas? My husband doesnt want to try again if I miscarry again. We cant take the heartbreak. What do I do?
