Confused

Ok so I wasn't going to even bring it up, but I'm confused and need to clear my mind. Monday night we had sex and after about 1/2 hr or so, I went to pee. On the tp was blood. Red/pinkish. I instantly freaked thinking things were starting, grabbed my underwear to see if they were ruined, nothing there. Wiped again and nothing more. Went to the bedroom and turned the light on to see in there, nothing there. So it had me awake for a while thinking for sure that something was going to be starting overnight. Oh and I was always crampy at that point. So after a few hours, I sucked it up and went to bed with a pad to be extra safe.
Yesterday morning I wake up to nothing at all, not even spotting on the tp. Cramped a lot all day yesterday and was on constant tp check anytime something felt weird. Not a single spot all day. I have all the signs that it's coming. I'm crampy still. I'm exhausted. I want chocolate or junk food. The weird part is there isn't any boob changes right now. No pain or anything there. Usually for me they hurt a few days before things start. So I really don't know what to think. I sat down and went over my chart, and based on pains, I think I ovulated on day 25. And today is day 38, so it puts me 13 dpo. I can't test. I honestly can't bring myself to do it, see the negative and totally give up yet. I figure if I make it till Saturday, then I will give it a try. Part of me really thinks though that this is over and it's just a day or 2 till it shows up. Should I wait longer than Saturday to test? I am scared here! And crazy....
Oh and he is totally cut off till we know for sure, and poor guy if it turns out to be positive this weekend, he is going a long time before I will trust sex again.
