A few days ago I had streaks of blood which were obvious, but didn't last longer than a few hours on and off. I was pretty shocked as my period was about 2 weeks away and this never happens (not even ovulation). The next couple of days, my breasts started getting sensitive. Now they're quite sore as well, but one more than the other. My nipples are actually very painful (mainly on one side). Sorry for TMI! I don't think I'm necessarily pregnant, but would lile some insight from experienced mums. What would be your guess?
