Pregnant and working

So I told my co workers I’m pregnant when I found out as they were all included when I had my recent miscarriage in feb 2019, there are only three other girls not including myself in the office. Lately I been feeling like one of the girls have been mean to me for no reason ever since I told her, not sure what I did we always got along and is considered my friend as well. She picks on any little mistake I made and turns it into a big deal I.e. one typo or a scheduling error. I just feel like I hate coming to work now😔 I would like some support am I being over emotional towards the situation. She is able to have kids as well so she wouldn’t be jealous of me being pregnant. I just don’t know what to do🙁
