My boyfriend and i are 18, i had a past miscarriage and im really scared of miscarrying again if i come out pregnant.. i have RH - blood but my first miscarriage was due to too much stress going on with my ex and family because i was 16. My current relationship is stableand we are so happy! No stress what so ever, but im just scared something will happen again, were also following this app for ttc, any advice?..
