Fatigued, Emotional, and Gassy!

I'm 4dpo and we BD 2xs with preseed. I've woke up late 2xs this week which is unusual and missed my exit home a few times. SO bizarre. Every morning I wake up super bloated and gassy all day. I saw friends hugging in Zumba and it made me want to cry...lame. Idk. I did have a little mucus come out this morning...But I should be drying up right? I hope these are bizarre signs of early pregnancy but I know it's to early to test... I'm so exhausted y'all. Hopefully I'm not psyching myself out.
