did anyone experience lower back pain? im having lower back pain in the right side but it's different from any pain I've felt, I noticed it when I was doing some laundry yesterday when I was bending. I'm also a smoker and yesterday afternoon I couldn't smoke without coughing, thought it may have been some allergies and I had some flu like symptoms last night. this morning when I woke up I tried to smoke a cig and I couldn't take the tinest puff without coughing so I put it out anyone else have symptoms like this and end up with a bfp? I think I'm 7 or 8dpo as I got normal ovulation symptoms early this month.
