Am i pregnant - contains graphic detailes!!?

I'm TTC and had on every day for 4 days leading up to ovulation and the day after. Around the time i was expecting my period (there irregular) I did start bleeding. At first it was brownish and this bight pink colour and came and went very lightly for the first 20 hours, then it stopped for a little while then came back but red and slightly heavier. It only went for about 10 hours off and on and no where near as heavy as my period nomaly is and not as long. the whole thing went for less tehn 2 days. I should also point out that i was having when i wasnt spotting/bleeding, before i started bleeding red. So i was immediatly suspicious . . I also had tingling , but they dont feel swollen at all, just very sensitive. I've had headaches, and lastnight when i would have been exactly 4 weeks i felt ill, which is very uncommon for me.I've also had period style cramps for the last 3 weeks but they come and go. My skin is far more oily then usual.
