My cycle is usually around 30 days and have been TTC for about 3 months, my partner and I have had a fair amount if sex, my period is due in about 6 days but yesterday had really faint pink when i wiped, i thought i was my period but today its still realllllly faint and is slightly more brown, I typically have really heavy periods so this is really unusual for me. I took a test the day before I saw the pink and it was negative. I went doctors today however and they said I could have a UTI but i have no symptoms of one, when would you advise taking a test again and could it have been IB?? TIA xxx
