I'm so confused!!!

I hope this is the right thread to post in!!! I'm now 2 days late but for the last 6 or 7 day I have been have symptoms like bad nausea, frequently peeing (I mean a couple times an hour), boobs are a little bigger (my husband has even commented on it), some food smells drive me to start dry heaving and now I'm having like a pressure feeling in my right ovary (it doesn't hurt but it's definitely noticeable). I took a test a couple days a ago and got a positive but I guess it was an error because the clock on the digital test never disappeared. I took another test this morning (with my second pee) and it was negative!!! I'm going crazy what do you guys think? I can get into my doctors for a couple more days!!!
