Twins maybe...

So I've been sick as a dog since I was about 2-3 weeks pregnant. I quite literally cannot stop peeing. I'm only 7 weeks and already the peeing myself has started and I drink everything in site like I feel so dehydrated. My lower abdomen almost the top of vagina is so sore and crampy, it just feels like constant pressure almost like constipation but I've been going just fine. I can't sleep for getting up to pee every hour on the freaking hour and waking up to crazy as hell dreams about my kids... I've even started dreaming about twins... And I swear to god my lower tummy feels like gold fish swimming in a bag like its weird it's just flutter type feelings (which could be gas I suppose but if it IDK where it is going cause I haven't been gassy) Am I loosing my mind?. My first doctor Appt to confirm was at like almost 5 weeks and she did three of the dip sticks because the test line kept taking taking all the ink out of the control line... They did not do a blood test so I have no clue what my hcg levels were... But did anybody just kind of feel like they knew it was going to be twins?
