First trimester spotting is normal. I spotted all the time when in my first trimester. 30 weeks in two days for me!
Not trying to get too personal but were you intimate with your partner before you saw this? Sometimes I spot a little and have light cramps after but its completely normal.
Some brownish tint is normal but not bright red.
Hopefully you can get checked out to verify.
It might be nothing but i think its best (for ur overreacting side of brain ;-) ) to check it out. .. Good luck
