What do you think?

My husband and I are ttc. My period is 3 days late. I took a cheap dollar store test last night but it came back negative. I have a regular period so idk what’s going on. I’m hoping it’s a baby in there. But last night I didn’t go to bed until 2:30 and woke up at 7. Idk why. I usually go to bed at 10. I’ve been really gassy for about a week. I’ve also been sleeping a ton. My cm is this white creamy and it’s a lot. What do you think??
