Not Excited.

Found I was pregnant today, I'm 4 weeks 4 days. Told my boyfriend and we are happy BUT after having 2 previous miscarriage's we arnt as excited as before. I feel upset because it's like that has been taken from us. Does anyone else feel like this? I feel like I can't get excited untill 12 weeks just in case it happens again. 😔 I'm literally so nervous and every cramp I get I'm running to the bathroom to check if if I'm bleeding! I know it's mad but how can I relax with out worrying it will be the same this time around !?!
