Baby or Job?

B
I just started a new job a 6 months ago. I have my own insurance they don't offer it through the job I'm afraid of getting pregnant now because I have just started the job. I've been so used to working in fast food restaurants and I finally launched a great office job making double the money. If I want to take a day off i have to notify the owner and he has to cover me, which is why I am scared to get pregnant right away because of the days off I might need in the future. I also don't want to wait to get pregnant because my boyfriends mom is willing to take care of the baby while I go back to work, and take the baby to every doctors appointment if I have to work so I have everything ready to go. I'm just so scared of losing my job once I get pregnant because this is not a job where I necessarily get sick time. My boss has 3 kids and adores children and seems to be very understanding when our tenants are late on rent. And he has mentioned to me that he really wants to continue working with me for a long time. What do I do????? Please help!
