2 missed it's now and no answers. Hospital wont do blood test or ultrasound until a pos hpt. I have many symptoms even Montgomery tubercles! Also random light cramps. Still nausea. Acne. Blue veins showing on arms, breasts, legs. I'm tired of hospitals thinking I'm nuts. I also got really wet during sex more than ever. I'm going on a week long trip soon and I just want answers.
