weird question

My husband and I had sex yesterday around 4pm and I've been losing my mucus plug for weeks now. Yesterday after sex Braxton hicks contractions picked up, some slight cramping but nothing crazy. I wake up this morning and wipe and theres a huge chunk of what looks like mucus plug, wipe again and another massive chunk. this continues to happen and I couldn't get fully dry wiping no matter how hard I tried.

My question is, is this in fact my mucus plug again or left over sperm? it looks no different from the other plug occassions I've had, but I've never had this much of it.
