Orange/pink discharge after sex?? Help!!

Today is 10dpo, I have had very sore breasts and nipples for about 4 days now with like stand out veins all over my boobs. Very full heavy feeling like pms boobs +some. My DH and I had sex last night and when I went to the bathroom I wiped and there was a orange/pinkish discharge on the tp. No pain or cramping. I do feel this could be our month but you never know until you test. AF is due on the 31st. Has any of the other preggo mummy's had this in super early pregnancy?
