could i be pregnant

I have pregnacy symptoms monthly before my cycle so i dont get to go off that. But i am getting an odd sensation sometimes while having sex. if that isnt enough my husband says i am cumming a lot more and i cant seem to get enough Dick.... could i be....oh i randomly cried for no reason today and i just feel off. i am getting splitting headaches, my boob seem different more than whats normal for me. plus i have sleep difficulty all the sudden and wake up 8 times a night to go pee.
