Trying to conceive

I’m about 8-9 DPO, I started experiencing really achy cramps at 4-5 DPO felt like af was coming lasted about 10-15mins. At 4-5 DPO I’ve been experiencing constipation which I never get I’m pretty regular. Constipation stopped a day. Today at 8-9 DPO I realized i’m constipated again. I had coffee this morning and that usually makes me go. I didn’t go until now. Could this be a sign of pregnancy or just progesterone messing with me ? The constipation is very new for me…
