Is it normal to have pinkish spotting with progesterone suppositories?

Ky 8-15-17👼🏼 & 10-28-17👼🏼 Pregnant with my🌈💕

Today is 14 days since my trigger shot and I've had strong positive tests since Wednesday. This morning when I put my progesterone suppository in there was some pinkish discharge on the applicator when I took it out. Is this normal????
