hi i took two pregnancy tests int the evening, one to test and the second to confirm. the first test came up with a dark positive response line almost straight away, and the second was fainter but still there, i asume because i had already peed and then my urine was slighlty diluted after drinking lots of water. my question is as i have irregular periods would i be at least 10 dpo? me and boyfriend trying to work out when we conceived. also i had sore boobs which is why i thought something was up and decided to test, because my boobs are never sore.
