It's hard!!!

Been trying for 6months, working to have another baby. But then i think can I even get pregnant again, I wasn't suppose to have my daughter. I have a Bicurnate uterus or heart shaped uterus. It's hard to deal with these emotions sometimes......my daughter and fiance get so excited and every month I feel like I'm letting them down. We inseminated on the 28th with ovulation following on the 29th........forward to today and I'm 4 days late, with no positive pregnancy test. Even with my D&C's I had positive test......I'm so confused and my OB

doesn't listen.....ugh! Any advice????
