If you have not been pregnant since, an examination by a Gynecologist
may be able to tell you if you were ever pregnant before.
That early in the pregnancy the miscarriage is usually like very heavy period. Lots of blood, usually cramping,.
I hope you will seek professional help. This type of trauma can be held in, but someday it could all come to the surface and could be more than you think you could handle. Better to deal with it now with guidance, than end up a wreck, lashing or acting out because it is too much pain.
I am sending you strength.
