Bloody show?? Maybe contractions?

This may be tmi for some but need some insight. Around 4pm I had some strong pains in my lower abdomen. Then I started passing gas so I figured that's what it was. Around 530pm I went to the bathroom and when I peed and wiped I noticed some blood on the toilet paper. But every visit to the bathroom since I haven't seen the blood again. Was that my bloody show?? Also the pains in my lower abdomen haven't gone away even after I used the bathroom. Are these contractions? I haven't been timing it and I'm not really sure how to time them. It's currently 620pm
