Trying to get pregnant again after miscarriage

Last yr Aug 2022 nung makunan ako. Tanong ko lang po mahirap ba talaga makabuo ulit after miscarriage? Medjo nakaka frustrate lang kada nag nenegative yung PT ko. Always taking Folic (Quatrofol & Ascorbic acid) po ako as per OB advised to continue taking Quatropol until I get pregnant again. Maraming Salamat po.
