Did anyone else have spotting while on progesterone suppositories???

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

I'm on progesterone suppositories and take one 100mg pill vaginally two times a day. I've been talking them for two weeks now and have had red spotting the past 3 days off and on. It'll turn brown, then pink, sometimes nothing, then back to bright red. I asked my specialist if it's normal to have red spotting and she said she would expect that with suppositories. Happen with anyone else???
