I have been having unprotected sex with my husband for 3 weeks and we are TTC. For some reason, I feel like I might have conceived. My period isn't due until the 14-20th of the month but I'm desperate to know. Have a little cramping and just saw a little pinkish blood when I used the restroom, which led me to think about it more. Any advice? Serious people only please, since I've seen some harsh comments on other people!
