I am a bit of a worrier and have been feeling very strong kicks/punches etc. Due to my job I am out travelling a lot and often find myself running across stations and up and down stairs to catch trains/tubes and hurrying between appointments on foot. Although I have been feeling really strong movements, some days seeing my skin jump out! There are some days I don't notice anything at all, even when lying still on my side at the end of the day. I had a really busy day yesterday, ran for two trains and then had to stand (as there were no seats!) for the two hour long journeys. Now today I really ache in my groin and I've not noticed any strong movements other than the odd squirming sensation in the last 24 hours....is this normal just because I was so busy and rushed, or should I be worried....?
