I have had the same since yesterday. The tears are very close. Espesially if I have to climb the steps at work, which is quite often as our bathrooms are on the ground floor and offices upstairs.
I really don't see how people can say 'Oh but that's normal'. It is not normal to feel this way. Luckily there is only 11 weeks left.
Best of luck to you.
I had pain in my groin a few days ago and walking was agony, my baby is head down also, my obstetrician said it was growing pains, I'm 28 wks
