As the title says does any one experience lower back pains during or before ovulation? I'm worried I've missed our chance. I took an opk yesterday morning and it was negative and this morning woke up with lower back pain did an opk and it was positive. We didn't get chance to dtd yday as partner was away for the night, last time we dtd was Friday morning, if we dtd today do we still have chance? I feel like I'm ovulating now and it's too late
