Help! Could I be pregnant 👶🏼

Hi girls, I really need your advice, I haven't come on my period yet this month (may just be late I know) but wondered if you could give me some advice of things I should look out for, I'm giving myself to the end of this week to take a test as today is the day I "believe" my cycle should be ending (which hasn't yet occurred) but while I wait with my fingers and toes crossed to take the test is there anything I could be looking out for? I seem to be having more wee's than normal but that's about all so far! Thank you For your help in advance!!
