could it be the baby is on your sciatic nerve? its fairly common. I get groin pain after DTD due to the swelling and my gross vacrose veins down there... other times i get groin pain from a full bladder or bowel (everything competiting for space??!!) I also have been getting crampy pains irregularly and can be triggered by DTD (altho i mostly only get BH 30mins or so after) for at least 8weeks now... this is my 3rd and ive had more BH and fake labours with this pregnancy than the other two combined! Best of Luck!!!
