Things have changed and I didnt even know it!!!

Where to start.... Last night i think was the worst night ever started of with one of our employees texting us and saying they are quiting great now we only have 2 tattoo artist and its slow season what the hell are we going to do??? So of course that started a fight with me and my husband and that got even worse he wished we never did what we did and said it was my fault that im depressed and upset all the time and that this is the most stress he has ever had!! What do I do with this??? I am now 17 days late and still no sign of AF. I go to the Dr tomorrow and i dont even know what to talk to her about? I swear i am pregnant now! i have never been this late the only time i was is when im pregnant. With my youngest i didn't know i was pregnant until i was 4 months no signs slight spotting when it was my period. im having some symptoms now that i have had and some of them go away i dont know what to do. i didnt know my husband changed his mind on this i dont even want to go to the dr just because she is going to try and set up next months iui and what do i say no cant im so confused i didnt thing this would tear us apart i thought it would bring us together!!! How do i change my mind into not wanting this as bad as i do? How do i stop thinking and praying and wishing i could have another baby? Am i selfish because i dont think that i can ever stop wanting one or even two! I dont know how to think any more i give up im so frustrated what do i do with all this????
