Does it sound like I'm pregnant?

I have a doctors appt on the 30th so for now im just asking questions before then. I think im pregnant and we have been trying for about 2 months now and I thought I was pregnant in dec my period was from the 4th -7th and then riht after that we had unprotected sex many times thorugh the month I started having some cramps, which I’ve never got and they werent that painful just uncomfortable, my stomache was getting a little bigger and I was constantly always sleeping, but then on dec 30th I got my period again which I found weird and that lasted until jan 2nd I think. since then we have continued having lots of unprotected sex and I’ve even been taking prenantal vitamins. my stomache has grew and now I cant due up my pants without feeling uncompfortable or some pain. its mostly all under my belly button thats been getting bigger, I keep going back and forth between loss of appetite and constant hunger, but I love chocolate and use to eat it a lot now I cant really stand it, its just something I never feel like anymore. same with ice cream I’ve also been so tired and its really hard for me to lay down without falling asleep imediatley, or even wake up easily in the morning. My boobs have gotten bigger and my nipples have even got darker and there are many noticable whit dots on my nipples.I sometimes get cramps and recently I’ve been getting the puking feeling and then once and awhile acid will come up, my mouth feels like theres more spit always and I’ve had a stuffy nose, with hiccups and gas.

could I be pregnant. I really thought I was but then now for the second time I’ve got my period again in the same month except this one is 5 days earlier now and it goes on and off between red and brown?

I hope more then anything I am and I hate this disappointment. and my periods are acting so weird.

please helpp!!
