39 weeks and brown blood in toilet and wiping

Taneesha

Been having irregular stronger contractions yesterday. And ALOT of back pain currently. I did get checked yesterday so wondering if the blood is from that but Iv never bled from a cervical check n this is baby number 3. I’m 2cm dilated and 90% effaced. When I just got up to pee saw blood in toilet and when wiped. Any one experienced this? If so when did baby come? Thinking it could be dilation idk how to time back contractions 🥴
