Im a ftm but ive been really tired since 4 weeks. Im 13 weeks now & they say you're supposed to get more energy in the 2nd trimester, but hasn't happened for me yet. & I say only get married if it feels right dont let it stress you out. As for memorial day weekend I would just try to find someone that is reliable to be there in case you do need to go to the hospital. I would try to set it up early that way you have a plan in place
