Can't I Enjoy my Pregnancy and Be Happy!

Well I am 8 weeks pregnant with Twins thru IVF.  I am 38 years old, my SO and I have. 17 year old daughter which took us 3 years to get of with her. After having her I got PG again a year later but turned into a Ruptured Eptopic Tubal pg 2 days after finding out. The thing about that pregnancy, I felt something was wrong.  I remember telling my SO that morning when he asked how his baby was, I told him idk I don't feel right. I don't think I'm going to make it until the end.  A few hours later the pain came on...  That was 15 years ago.  Since then have gone thru 3 cycles of IVF within the last 10 years. So decided last year we will give it one more try and was finally blessed with 2 little nuggets. 😊 so far everything looks good, saw and heard the 2 heart beats in week 6. And I go back for my last OB visit with the IVF Clinic next week at week 9. Anyway, I feel so good about this PG and so positive, and so happy.  We have announced it to our Closest family and friends. My family has been so happy and supportive... But some of his family and some friends... I know they r concerned but will make comments like.. Oh I'm gonna pray for you that everything turns out good BECAUSE it's still early.  I take offense to that because I feel that they r being negative about it. So it then worries me. Or they will tell me stories like my firmed of a friend was pregnant and she had miscarriage, etc. 😞 Makes me not want to tell anyone anymore.   How can I respond to negative comments and let them know that I am happy and idk want to think about stuff like that, air Just pray for the best as well!
