I am not too sure whether i am just being silly and thinking too much into it, or whether i am actually pregnant.

I had unprotected sex most days of the past month since my last period, plus on all of my fertile days, after around 8 days approx of ovulating i had unusual cramps (werent painful) that lasted for 2 days, on and off mostly had them at night.. Never experienced it before, it felt really weird. During them 2 days i also had hot flushes on and off through the night, again i dont normally get that. Its now about 2 weeks since this happened, and ive noticed this odd small shaped lump sticking out of my pelvic area it is really reaally tiny. i have a flat stomach normally and for the past week have been extremely bloated, and now when i breathe in you can just about see/feel this tiny tiny lump, but its only on my left side which i thought was odd. I had a mild headache yesterday but nothing bad, and my teeth have been extremely sensitive, my boobs have got bigger and more swollen/feel heavier/sore then usual, and i noticed today that they were darker-which ive never seen before as usually they are very light and pale. Before i come on my period i normally have a headache which is more like a migraine and i am normally sick or feel extremely sick so much i cant do anything but i have not had this yet. All the symptoms i had, may just be because im supposed to be coming on. My boyfriend has just dismissed it and says its in my head, but what concerns me is the lump, never have i had that. if i do not come on tomorow, then i will wait a week and then test, but what do you guys think?
