Scared to get excited

I miscarried on 11/9 and was done bleeding by 11/13. I never had a period and tested out of curiosity and am now pregnant again. I'm terrified though. I have one other pregnancy and a five year old son other than this one that ended in miscarriage. I took my first test on 12/11 and a few more since then. I would only be about 4 weeks though. No symptoms other than being sleepy. My breast aren't sore and I'm not nauseous. Thoughts? Is it ok to not have any symptoms? Are the odds in my favor? I'm so scared
