Help!

Dani • Hello! I am 25 and my BF is 30 and we are TTC a little bundle of joy! 😀
Today will be 5 days and no sign of AF. Took a pregnancy test last night, negative. Took one this morning and it was negative as well. Has anybody else had this problem before and ended up pregnant? I have a doctors app the 28th but like most, im just a little anxious. 😁
