So, we had sex peak O day, and I had such strong Prego symptoms, I was certain I was pregnant. 10 dpo I started spotting light pink at night with a little heavier bleeding (enough to need only one tampon, rest panty liner).. Today it's back to light spotting pink. I want due til Monday for my period, so this was 5 days early. Anyone else have this happen and it end up being pregnancy not period. It's the heavier day of medium bleeding that is throwing me and it's to early to test.
