Please put my mind at ease. Temperature during pregnancy.

Ok i know im one of those crazy people who worry too much. After 3 miscarriages it seems impossible not to worry about everything...though i wish id just let it go! Im sure once i finally have my furst child I'll worry lesd next time but for noe i just want my first child here safe. I have done my temperature each day since i have been pregnant just so i could give myself peace of mind everything is ok. My temp since being pregnant has always been around 36.7 degrees ...sometimes higher. Im 17vweeks and 2 weeks ago my temperature dropped to 36.5 degrees and today 36.4 degrees. Am i worrying about nothing? Is this normal. I had in my head that when pregnant your temp stays high?? Thank you!
