Pregnancy?

destiny

So a couple weeks ago I took a pregnancy test and it came back positive but every one I’ve taken since have come back negative. My mom keeps telling me that she thinks I’m pregnant and so does my boyfriend but still every pregnancy test comes back negative. My boyfriend keeps telling me I’m glowing my boobs don’t hurt but my nipples are relatively sensitive I’m sleeping alot more I’m always tired and I’m eating more than normal to be more specific I’m eating a lot of baked goods like brownies cupcakes cookies. Any ideas?

Also I should probably mention my period is 4 days late.
