Positive test and spotting.

I spotted 10 dpo for one day. I'm now 15 dpo and got a positive test yesterday and am spotting.

I don't know if its from Sunday when my partner hit my cervix really hard and I bleed or if its from me cramping on my left side. I'm worried. Anyone know why I would be spotting and cramping on my left? They are light cramps but they are frequent.
