my period started on thursday, and it was very heavy throughout saturday. it started lighting up on saturday night. i woke up this morning (sunday) and my pad was clean. it burns at the end of urination, i think i might have a uti but i’m not sure yet because i haven’t gone to the doctor. but i just went over and it burned and there was a tiny amount of blood in my pad. i wipes and there was light pink blood. am i pregnant??? i’m very stressed as i don’t want to be pregnant
