I have endometriosis on rt ovary, and 1st month pregnant does this alter implantation ob/gyn prescribed: progesterone 400 mg+vit e&c+aspoci is this safe

Having endometriosis: On right ovary after you are already pregnant in-and-of itself does should not alter implantation. Without knowing your specific history, giving Progesterone is not generally necessary, but some will do it when a patient has "shortened luteal phase". I would speak to your doctor and ask for clairy as to why he/she is putting you on these meds. Vit c and e, do not benefit. Aspoci?
