Blob of jelly discharge ?

Okay so a little background story on why I’m worried. I had unprotected sex on January 14th. My period is normally spot on with the expected date which was like the 25th of the month or so but it didn’t show up until February 13th & when it did it was kinda weird. It was really heavy the first two days & then really light the other days (my period is usually really heavy to the end).

So anyways, while waiting for my period I was experiencing all the pregnancy symptoms: late period, changes in my nipples, headaches, that “wet” feeling down there but never actually being wet, etc. But then my period came so I guess it was all in my head .. ?

Now this .. any idea what it might be ?
