After We had sex tonight I noticed a light amount of pink blood when I wiped. Mostly creamy mucus with soft pink tinges. I am suppose to start my period on Tuesday and my cycles normally run long but I can't help feeling like this is a sign I could be pregnant. I am also experiencing slight nausea, frequent urination, heightened sense of smell, tender nipples and breast, dull cramping in abdomen, and I'm always so freaking tired!!! I mean I literally slept for 15 hours on Tuesday! Be honest guys what do you think this could be? Im considering taking a test on Tuesday if nothing else occurs. Thanks for voting :)
