Am I late?

Mrs
Hi all, 
New to this to please be kind 😘 I recently got married and am now trying for a baby - I went on my hen do 12-15th May and started trying straight away after I was home. My period in May started on the 3rd May and lasted for 4 days. I still haven't come on - my periods are very regular and in April I come on the 3rd Of April which lasted for 4 days also. Could I possibly be pregnant? I really don't want to be doing loads of tests so early on trying... hope someone can help ❤
