I have been through this lately and God was it embarrassing with two boys, but my husband is a gem, he ensures that I have all the privacy possible. Adult diapers help and so does having a nice thick dark cotton cloth on the car seat. I usually keep sipping water in which I add a squeeze of lemon and salt to keep me from dehydrating... and getting too tired, I tend too if the flow is heavy and the day is hot. Every chance I get to change I grab it with both hands... keeps me comfortable and less irritable. You really need to see your gynecologist if this problem is new to you... there could be other underlying causes.. take care. Have a blessed day!
