I get so happy when my son moves around but I still have the pregnancy mindset after losing two babies at 5 months.... it wasn't due to any defect just a weak cervix....now that I'm a couple of days away from my 3rd trimester, I keep thinking the worst... I mean I still haven't told everyone I was pregnant (family included) I keep pushing it off.... at first I said I would tell them after 12 weeks... then after 16.... then after 20... now I'm 26 weeks and keep thinking "what if this happens" ughhhh and I keep telling my husband about my fears but he's so excited that he has his own mindset about the whole thing... he started telling people right after the pregnancy test came back positive... I just need words of support and ways to keep my mind from thinking negatively
