TMI could I be pregnant??

My period isn't until the 17th and I've had a show and nothing since, me and my SO have sex regularly sometimes up to twice a day. The only form of protection we use Is my coil and he doesn't pull out. I'm concerned my coils been knocked out of place as I experience pain after sex for a while. I've been feeling really tired and run down lately and pretty emotional. I phoned my clinic to see if I could get a check up on my coil but I'm working on the days the doctor is available. I've attached a picture of the spotting that I have had today and had nothing since
