I live with my boyfriend and his family (his mom, 2 sisters and a sisters boyfriend). a couple weeks ago his oldest sister had a miscarriage.. now she is trying to get pregnant.. our menstrual cycles are in sync when hers changes mine changes.. usually I get it a couple days after she does or after she’s has stopped it and I have not gotten it yet.. not really sure how late I am but I am definitely late and keep thinking I’m getting it but when I go to the bathroom its just gooey discharge.. I took a pregnancy test (as did she, irrelevant) and it was negative.. I will take another in a few days.. I just want to hear some peoples opinions, what do you think is going on?
