Strange Discharge

Me and my boyfriend used pull out (it's not the first time, but the only time this cycle) two days before my suspected ovulation date. On my ovuilation date, two days after the sex I passed a clot looking thing and found it in my underwear. The clot was 1/2 an inch in length and it looked like a gel candle with a red spot. To be more descriptive, it was a bubble of a non liquid substance, completely clear with one little red dot on one side. I've never seen anything like this and i'm wondering if I passed the egg? Could this be a really early implant? Do you think i'm pregnant cause i'm not due for my period for another two days and I am showing some normal signs of my period (sore breasts, tired but cannot sleep, irritable, crying, skin problems) but i'm still worried ( I worry about every other month becuase/ my boyfriend never learns to respect me and I never learned to respect myself ). Could it have been the egg?


Should I worry?
