Bleeding 35 weeks HELP

Hi all, I had pink spotting on and off since yesterday. I’ve been in contact with my doctors office multiple times, and when spotting turned from pink to red I went in for a NST. Spotting had gone away by time I went in for NST, which was about 4:30. No contractions and no concerns so they sent me home. Around 6:30 I had the smallest clot/possible bit of bloody show...it was honestly the size of a bloody booger not to be too graphic, but then had nothing else for a while. I just went to the restroom and this happened. I really don’t want to go back to hospital for nothing again, AND to top it all off me and my husband are the maid of honor and best man in our best friends wedding this weekend! Has anyone had this happen? I still don’t feel I’m having contractions, but I’m a FTM so I’m questioning myself.
