Hello.
I am 17 weeks pregnant. Went shopping today and parked in overflow car park. Bought my food shopping in one large bag. Got to end of car park and couldn't take trolley through. Carried bag to car. It felt ok to start, but as it was a bulky bag was arkward to carry and felt very heavy by the end. Got home and now have on and off pains in my groin and bump especially on opposite side to bag. Also have feeling of a heavy cervix. Is it likely to have caused any issues or just likely mildly strained a few ligaments and muscles down there? Just worried I have done some harm. 
I wish this pregnancy lark was easy! Keep feeling like I should be able to continue as normal, but body saying otherwise.
