Tested Early and got BFP

My husband and I have only been trying for 2 months. I have been so tired, felt "different", and my boobs are so sore! I am only expecting my period on Friday but I took a test anyway. Well... 4 tests. All BFP within seconds! I'm worrying that this could be a false positive because it's so early? I'm worrying, but I'm trying to stay calm for our health. I am probably at most 2 weeks. Any advice and just talking about it would greatly appreciated! Thanks all!
