My husband and I had sex 3 times before during and after the day I ovulated (a heavy clear discharge day mid cycle)...and are trying to get pregnant. About day 20 of my cycle I was woke up from a pain in my lower back on the one side that at times shot down my butt! It last awhile...and when I woke up I was still uncomfortable...and after awhile it was completely gone for good... Could this be implantation? This would be my 2nd pregnancy...but I dont remember FEELING anything like that 6 years ago.....ANYONE in the same situation?? Or COMMENTS?
