ok, so my last cycle was sept 15-20, i had u/p sex on the 24th the 30th and the 1st. on the 25th i had very light spotting (light pink only showed up when i wiped). two days ago i began spotting again, but it has gotten increasingly heavier, not as heavy as my regular period but enough to wear a pad or just one tampon a day. its a dark red/brown color. it stopped early today completely. i have been experiencing all of the early pregnancy symptoms (sore breasts, nausea, cravings, heightened sense of smell, monster headaches) my regular period isn't due until tomorrow. i have been searching the internet like crazy to see if im the only one experiencing this, and i have found many women have had heavy period like IB. can anyone give me insight? has this happened to you or someone you know? serious answers please!
