Right ladies need help/advice

So I'm not currently due on my period for a week or so and let's say Tuesday I went to the loo and wiped seen a bit of pink on the tissue so I put a pad on thinking I came on early went to bed as normal woke up nothing in the pad.. Wednesday I wiped again and there was pink also it's not heavy enough to be a period it's just when I wipe had a few cramps but not too bad could you possibly give me some advice of what this could be it is only when I wipe... Cheers ✌🏼️
