Early spotting!

I just found out yesterday that I’m pregnant. My period is not due until tomorrow. I’ve had 2 MC’s so my doctor prescribed me Vaginal Progesterone pills. I was told to take them as soon as I get a positive pregnancy test. Last night was my first one and I’ve been having pink spotting off and on all day. I’m really hoping this is because of the pill and not another early MC. 😩 any similar stories?? Top test is from this morning and bottom is yesterday’s!
