Pregnant?

Sooo our little girl is about to turn 1 in July. Well my husband and I did the deed and didn’t use anything and I never have done birth control. Well my period should have started in the 21st. I’m usually before anyone at work and they all have started. Should I test? I wiped Saturday evening and there was light blood but nothing before or since. And that usually doesn’t happen with my periods. I’m confused lol! It took us 4 years with our first. Will it only take 1 time with the second😂
