13dpo anxiously waiting

I am 13 dpo and anxiously waiting to take a test. I did test 8,9and 10 dpo because I have heard of women getting positives, negative each time.I do need to take into consideration I have low hormones and had to get them balanced these past 3 months. Taking prenatal for 3 months (and continuing) and estrogen for a month. Hoping I getting my little baby this month. Have any of you test negative before a positive and was your positive after missed period?????
