Is the 'Umrah valid with two light drops of blood on the 'Ihram due to a fallen tissue that was placed on a pilonidal sinus wound?

The sin you committed while in a state of ihram does not invalidate the Umrah or the ihram itself. However, it entails sin, the obligation to repent, and the sacrifice of a camel (badanah) to be distributed among the poor of the Haram. This sacrifice must be made promptly. Your Umrah is valid. The ruling on circumambulating (tawaf) while in a state of major ritual impurity (janabah) and the effect of impurities on Umrah have been detailed in previous fatwas. The validity of Umrah is linked to the validity of prayer with the presence of blood: if the prayer is valid, then the tawaf and Umrah are valid; otherwise, they are not, although some scholars consider it valid even with the obligation of offering blood.
