WTF??? SO GOING CRAZY RIGHT NOW....?

so i have been on the internet all day reading sbout how some spotting is normal during pregnancy however... i dont know if i am preg yet or not i think that i am but i try not to think about it so that if im not it wont be disappointment. (a little background info) my period are usually heavy i mean you know that it is a period. well my last one was 3/20 and i had 1 day of pink spottin on the 18 of april which is whn i was suppose to come on again. no period for the month of april. so no w we are in may and i am do again for a period on the 15th tomorrow. every since tuesday i have had some pinkish red spotting but not enought for pad not even when i look in the toliet when i get up only when i wipe and today i had a lil string of blood mixed with clear stuff but no cramps or nothing...im just trynna figure out what it could be...i know that is defintely not my period...im going for a blood test next week...but i was wondering if this happend to any of you ladies and were u pregnant or just having a moment. and yes i have been experioencing some symptoms...like urintaing a lot and headaches, heavy brest but not sore...if there is any insight to be shared please so share it thanks
