TWW and bored

Cu

I just had my egg retrieval which went very smooth on Monday. I only had 10 follicles and got 2 eggs out of it. Cried but then realized 2 is better than 0. Doctor did a 3day transfer and these babes looked really good all fertilized. Now it’s the day after my transfer and my lower back is in some serious aches. Is that normal & is there anything I can do to help it? Heating pad is out of the question. All I’ve been doing is laying on the couch lol
