TTC after miscarriage

Is anyone TTC #1 after miscarriage? Me and my husband we were TTC for 7 months until we got our BFP and at 3 months of pregnancy at ultrasound doctor told us that baby's heart stop, but I didn't bleed, so i had to get pills to start contractions and after 4 hours of contractions nothing happened, then two days latter i was running a little and at night contractions started again and i started bleeding really bad long story short i ended up having contractions for 4 hours again and passed out, my husband had to call ambulance cause i was pale. In ER they had to give me morphin and stop the bleeding, doctor said my body reacted diferent to the pills... So im really scared for this not to happen again... But i really want a baby more than anything
