General question about early pregnancy symptoms

Patient: Hello,I would like to ask about the most early pregnancy symptoms. My wife’s period has been late for about 3 days so far. She had spotting two days ago, she thought its a beginning of her period, but it didn’t started yet. She’s not so emotional as at the beginning of usual period. Her breasts haven’t puffed up like it usually does. Nipples are very sensitive (they are very sensitive during period as well). We haven’t done a test yet as its so exciting to realise it naturally. If you could please provide us with some guidelines that would me much appreciated. Looking forward to hearing from you soon.Best regardsLukas

Symptoms: Spotting, peeing
