Having some hopes down 11 weeks pregnant don’t know why people are always negative 😒

I’m 11 weeks and 2 days and so far my last 2 ultrasounds have looked great. Heard heartbeat at 7 weeks and 1 day at 164. Then did another ultrasound where I was almost 11 weeks and heartbeat was doing well again at 147 it was because baby was asleep and my ob wasn’t really concerned. She told me miscarriage rates drop when I’m almost 11 weeks and I have 95% chance of having the baby to full term. I was happy about that and decided to tell my best friend who is due in November and instead of her being happy for me she said they always say that that doesn’t mean anything that your good your still early. I don’t know if I should take it the wrong way and just trust my ob on what she said but I’ve had 2 losses and I’ve never made it this far in a pregnancy. She also said sometimes they don’t know what their talking about I’m just disappointed 😒 I have a 12 week scan coming next week and now I’m just nervous im not trying to let what she said get to me but now I’m nervous for my 12 week appointment and something might go wrong 😔 She was telling me stuff about a missed miscarriage
