So I got off my BCP the 5th of this month, had my withdrawal period the 6th-10th, and BD's the 8th, 11th, 15th. The 16th, 17th, 18th,(this Friday, and Saturday) I had really bad bloating, mild cramps and bad lower back pain, and Sunday and today I just have lower back pain only. I was wondering if these were all signs of early pregnancy? Implantation pain? Its too early to take a test so I wanted some advice on what i could possibly be feeling? Please help!
