I'm 9w4d and spotting (maybe tmi for some??)

Sandy • married to the love of my life, suffered a MC 8/27/14 but we are trying again. My 2nd his 1st
We had sex last night nothing crazy but he did "bottom out" a few times which was quiet painful as usual when it happens. This morning I get up and use the restroom and I'm spotting.... I've read online spotting after sex in first trimester is normal but I'm a little freaked out :(
