So sacred

Ayer suffering a miscarriage in January I finally am pregnant with my rainbow baby. I plan on calling my dr today to let them know. But last night was so scary I woke up with bad cramps in my in my pelvic arra and a shoptong pain down my leg I seriously though I was miscarry ing again but went to the bathroom and thank god there was no blood but I'm still worried. And I feel when I tell my dr about what I experienced that it won't matter to them. I would for they to say you can come in today but I know that won't happen. What should I do ?? And has this happen to you before and everything turned out ok ?
