5 days late, negative test


Hey guys!

My period is very regular comes every 25th cycle day. Me and my husband are actively trying to conceive. My period was due 5 days ago, no sign of period. I'm always on time. Last period was April 4th.. Nipples were sore to touch last week now they just feel a little bigger. Took a test this morning the dollar test. It was negative😥

What should i do ? Could i be pregnant?
