Spotting 2dpo?

So here we go. My doctor started me on progesterone on the 24th, had a positive opk the 28th. The 31st I had spotting, super faint spotting. Would that be something from the progesterone? Haven’t had any spotting since. So ready to testtttttt! Light cramping I only notice when I’m relaxing for the last 3 days or so, suuuuper tired and short tempered, and craving pickles...which I never eat. I had 3 tonight and it was sexual how delicious they were! But I can’t tell if it’s all just from the progesterone or something more 😫🤦🏼‍♀️
