Pregnant with Rainbow baby ...SO paranoid

I just had a miscarriage in May ( mothers day to be exact) and found out I was pregnant in June. I am really trying to not let my my fears of losing this pregnancy consume me but I can't help it. Every cramp I feel my stomach drops any bit of discharge I run to the bathroom to check for blood and I feel so awful about it! I just want to enjoy this pregnancy like a normal person. Any advice ?
