Anybody unexpectedly fall pregnant??????

I posted this in the first trimester of course the wording to will be different but I just found out that I’m pregnant with my fourth baby and I was on birth control awaiting my appointment to get the procedure of tubal removal and now I am just depressed I cannot believe I am pregnant three kids is hard enough for me more than enough to be honest I don’t know how I’m going to do this I never expected this to happen I know babies are blessings and I know some people aren’t lucky enough to have kids but that doesn’t change the fact that taking care of three alone while your husband‘s always at work isn’t hard I feel for the people that cannot have kids but just cause I can are you can does not justify the fact that We had unexpectedly fallen pregnant how are you coping with this situation I’ve only known for three days and I just don’t feel like myself this is supposed to be a happy moment but it’s not for me
