When I waa having my miscarriage I startes bleeding. It first started out small and brown and over the next few days it got to be more and bright red. There were thousands of tiny tiny blood clots. If you don't see anything, I wouldnt worry about it. Dont let your dad stress you out. Stress CAN make you have a miscarriage so just keep believing that you will be ok and so will your baby
Don't stress yourself out and don't over think it, some signs that would be seen as miscarriage is not. The more you stress and worry the harder it is on you and the baby. Don't think about it and just eat right, rest, and take it easy.
