calf/leg pain

I've been having a bit of pain in my calf I am 14 weeks pregnant I had it more yesterday but the pain would also travel towards my knee the pain wasn't intense it was mild but there and today most of the day i haven't right now it's there again but barely there I see no swelling or redness or anything out of the ordinary it scares me cause of blood clots but idk I do already have an appointment with my dr on Friday so I will definitely mention it but I'm also just wondering if this could be just normal due to pregnancy or possibly a blood clot ?
