Spotting?

Daschelle • Expecting rainbow 🌈 baby on December 22nd! So very excited 💖☺️

Ive been spotting for about 4 days now, period ended on 10/17, it started off as just old brown blood but now its starting to get heavier and its becoming bright red again, should i be worried? This is the first time ive had spotting for so long. I just got a checkup and they said everything looked great (in my uterus and tubes and everything else)
