progesterone and baby aspirin?

Hello ladies I've had 3 miscarriages in the past and just wanted to know is it safe to take progesterone and baby aspirin and prenantals together. The progesterone is suppositories i got a couple of months ago when I was pregnant. I took clomid this month to see if it could help me. My period haven't came yet and I have a lot of white stuff I'm not sure if I am but I wanna take measures just in case I am. I won't be testing until the beginning of next month. I hate testing to early and fail. Any advice or stories?
