So last saturday i had a positive test which i was really excited about then on tuesday night i started spotting so i took another test which was negative so i thought i wasnt pregnant well anyway i took a test today (the day i w meant to have period) and it's positive again 😐 very confused. Ive rang my doctors and explained to them amd she basically said they cant do anything as im bleeding i after wait it out!! Is this right x
