Pregnancy? Miscarriage? Or period?

I had my period may 17 and it was very light. I was have been having lots of unprotected sex... And I had a weird feeling that I was preg. I missed my period and it is now the 27 of June. I have all the symptoms... Tender soft sore breasts. I pee constantly. I crave milk I drank a gallon in two days and usually I never pee or drink milk. My tummy will hurt if I don't eat every couple hours and when I eat I get full fast. Not only that but I have been waking up at 5 and 6 wide awake but tired! It's like insomnia! In mid afternoon I get really apathetic and grumpy and I'm ready for a nap I have no energy. My lower tummy feels hard , harder then ever as if something is attaching to the skin, like a baby is growing. I usually can't smell anything and now I can smell everything. My skin has drastically cleared up and feels to soft on my face! When my tummy hurts it feels nauseous but I haven't thrown up, yet. This morning I walked for an hour and came back and when I peed there was dark blood sorta brown coming out when I wiped. I have peed several times since and half of those times a little blood came out when I wiped. I always have light periods so idk if it's my period or just bleeding. I don't feel any pain and I am continuing to pee a lot... Any assumptions? It would mean a lot!
