I'm in denial about pregnancy?!

My husband and I have been TTC for baby #2 after 4 years I finally get my BFP!! ❤️ We are so excited but I'm it's too good to be true. On the first round of Clomid we did it! I'm in denial, I've heard of women having false positives I'm scared to announce our pregnancy to family and friends if we are not. How true can this positive be?! Has anyone had false BFP? I'm only 15dpo
