Just buy a standard urine pregnancy test kit from any pharmacy. Use your first morning urine because it has the highest concentration of the hormone, and check the results in 5 minutes. Simple and direct.
As someone who has seen this often, the most reliable way is using a home urine test kit. Make sure to read the instructions on the box carefully, and test using your first morning pee for the most accurate results.
Ugh, the anxiety of waiting for those lines! Just get a home test kit, pee on it first thing in the morning, and wait. Try not to drink too much water before testing or it will dilute the results, trust my tired brain on this.
Testing at home can be so emotional and nerve-wracking. I suggest using a reliable home pregnancy kit with your first morning urine a day or two after your missed period. Wishing you all the love and a positive result.
