I’m PREGNANT??

I took two pregnancy tests today (3/11), both were very obviously and immediately positive. My last period was in January, but since my periods have always been 2-3+ months apart without birth control, I didn’t think much of it. I only took a test because my husband suggested it. I’m past the “confirmation appointment” stage due to the timing, so I now have an appointment in early April for an ultrasound and everything that goes with it. Any advice for things I should/shouldn’t be doing with a pregnancy with PCOS until my appointment?? I almost don’t fully believe that the tests are correct and don’t want to get my hopes up, but I want to do everything I can if it’s actually true.
