I'm stressed

Wendy
My fiancé left for Florida yesterday to pick up his son for the summer. He's doing a little transition time with his sons mom so he won't be home until the 4th. I'm due Aug. 2nd and I'm so nervous that while his son is with us we won't be able to get everything done before the baby is born. I called in to work yesterday and today to start putting everything together but I'm not nearly done. I don't get fmla for my work and I've gone over my allowed call ins this period already. I'm afraid of getting in trouble and possibly fired over this even though one of my supervisors told me not to worry about how much time I need off. It hasn't been discussed publicly. Also, I was supposed to start my summer semester on Tuesday (call in day one) but it completely slipped my mind! And today I was going to go but I was exhausted after working all night and taking my fiancé to the airport at 5am.... I just feel so overwhelmed. I'm sorry.
