I am 39 and started taking Loestrin because of a heavy period which I thought was a miscarriage. I have been taking it for 1 month now and woke up yesterday morning with severe back pain and cramps going down my thighs. I was unable to move all day and took more Ibuprofen than I should have. I have had cramps and bloating the whole month and have been taking the brown pills for 4 days now and just started bleeding today. I am unable to function normally with the back pain and my boyfriend wants to take me to the emergency room. Has anyone else had severe back pain? I have had 2 kids and it actually felt like I was having back labor pains. It was that bad. Please let me know.
