was it a period ?

hi so here's my story. I had sex at ovulation which was about the 11th. at 4dpo I started to get cramps, headaches, bloated creamy cm all common signs of early pregnancy. at 11 dpo I had a metalic taste in my mouth plus my other symptoms. i also started getting a light pink diacharge. This is odd for me because usually when I get my af i literally have no spotting it just comes full force. So I spotted for three days then at 14 dpo I had a day and a half of bright red blood with a few clots. my af is always regular and it lasts for 4 days.ive had no severe cramps which is also odd for me too as I get af pains day two. my period is never bright red and i never clot. after the day and a half I have now gone back to spotting very light pink but only when I wipe. also cm is very stringy and creamy with red mixed in it and still have pregnancy symptoms. I'm so confused? I have had a mc before but this is nothing like that I have no severe pains or anything. I read a theory about testing on an opk whilst your supposed to be on your af so me and my Mrs decided to test it out. mine was a very strong possitive whilst my wife's was negative (She was also on her monthly) I done a test at 13 dpo but it was a bfn. think I will test again once spotting has stopped
