Help me please!

Today makes 1 week of me being late for my period. I don’t worry about getting my period as much as I did before because my husband and I were TTC for a year and still trying now. My husband said that this is the most late I’ve ever been. I’ve been having cramps from time to time and would think that I should be starting my period but there is no blood at all not even spotting. My breasts would feel tender from time to time. I took a test today and it was negative but idk if I should test more later on throughout the week. I’ve never been pregnant before and want to know what your experience was the first week of being pregnant so I can know what to do. Thank you ladies much appreciated❤️
