HELP!

So my period is due in 3 days yet I’ve had 3 positive home pregnancy tests. Different brands and even the clearblue digital. Obviously I’m so excited and told my fiancé and 2 closest friends. Anyways I went to the clinic and they had nothing but negative news for me! Said my pee test was negative and then the counselor told me that I was a pretty girl and shouldn’t let guys use me. That I should proceed with abstinence “when you lose the baby.” After I told her I was trying. And she knew about my miscarriage in June! And then one of the friends I told said that I shouldn’t get excited because I’m more than likely to lose the baby. Did anyone else have all this bad news and have a healthy baby😔😔 feeling so discouraged..
