heard a pop

hey guys I'm almost 34 weeks pregnant and last night me and my husband decided to have sex. We'll while we were having sex we both heard a pop noise once. I kinda just ignored it afterward o got a little wet but didn't know if it was from me Cumming or maybe my water breaking. he also mentioned it to me afterward and said honey what was that pop noise told him I didn't know. then about 5am this morning I was sleeping and what woke me up was a little gush that came out went onto bed and on me. I'm so confused don't know if it's from him or if maybe my water broke. can you please help! thanks
