Thank you for your Q.
If you are experiencing pelvic area pain & spotting associated with it - it may be due to pelvic infection
but one also needs to make sure that it is not related to any complications associated with pregnancy
( of course it depends on your age, last period & if any contraception
is used currently)
I suggest get pregnancy test if in doubt & also you must get urine checked to make sure it is not due to urinary infection.
Other reasons why pain associated with spotting on toilet paper ( if coming from back passage area) - is piles/ fissure (pain will be more around anus) & constipation
Obviously it is importanat you get appointment with Dr to get thorough examination & also some tests carried out
Hope this helps
