I just found out I’m pregnant...

I’m going to the store now to buy more tests. I’m so scared, my husband and I are were not planning on having a third kid until at least 5 years from now. I get so sick during my pregnancies because of HG, and I just got a job as a real estate agent which cost so much money to get licensed and pay dues, and now I probably won’t be able to work because I’ll have a pic line and I’m on bed rest. My husband is so upset, and I feel awful that I can’t be happy about it. I’m on birth control, but I was on antibiotics too at the beginning of the month, so I think that’s how it happened. I’m so torn. Somebody please lend me some words of wisdom.
