Hi. I Recently Just Had Sex With My Boyfriend The

Hi. I recently just had sex with my boyfriend the day after my period. He pulled out and I'm also on the pill. A few days later I was in the tub and this weird thing came out of my vagina. It was not usual discharge. The top was firmish and tan and the end was clear and mucusy. It was about an inch long in length. I have a picture if that could help. I'm nervous about what it could be I don't think I'm pregnant and I'm just very curious what it could be.
