Qyla's mummy, I also had very very mild cramps at week 4-5, and also don't remember having it with my no. 1. Maybe with no. 1 I was distracted at work, and never noticed. Supposed to be the uterus expanding. But if it worries you, can always give gynae's clinic a call and ask if u need to see gynae. Of cos if bleeding and cramps occur together, go see gynae immediately.
Another reason for cramps, erm, ok, a bit gross la. Cos I had constipation for four days, ytd when tried to do big biz, half way thru started having horrible cramps, broke out into cold sweat and vomited. Hubby n I rush to TMC and even call my gynae in, cos it felt like uterine contractions. Diagnosis is purely constipation. Cure is use suppositories to ahem, unload. Baby safe. Moral of the story? Dun get constipated lol. Sooooooooo embarrassing.
Min81, so happy to see u here! Eh, i was doing ivf a while back too, so remembered your nick. Congrats! About your hubby's aches, my GP ever give me some sticky thingy to stick on my strained shoulder before, safe for pregnant women. Can he source for something similar? Also, I have a friend who stopped having bad headaches after cutting out caffeine from his diet ie. No kopi and teh. Dunno if this applicable for your hubby.
