trying to conceive, what could this mean?

[kirk]

my last period ended April 6 but it was unusually light and barely had any cramps (i usually cramp pretty bad) also I had light bleeding for one day about one wk before that period (first time I've ever bled between periods) My husband and I had sex on the 7 and 8 and also the 11 (but he didn't ejaculate the last time), my ovulation calculator said I was supposed to ovulate the 12 but I did not do a predictor kit so idk when I really ovulated. On the 11 after sex I noticed a small amount of blood on the tp when I went to the restroom and for about 3 days after I continued to spot (until the 14th) which is very unusual to me, its never happened before other than the time I mentioned above and that was only one day.. On the 15th everything seemed pretty dry but since the 16 I've had thick white discharge (no odor) also unusual. Other things I've noticed is small cramps that kinda feel like a tightening sensation in my lower right abdomen and a fluttering feeling in my whole Lower abdomen, and fatigue and gas. It just seems way to early to be experiencing this if its pregnancy, and if it is I woulda had to have ovulated early I think. But what do you think it could be? I know its not an std because I was just checked before my last period and I've only been with my husband. has anyone experienced this? What was it? What do you think it is?
