Hey ladies! So I'm 4.5 weeks, and over the weekend felt super nauseous and crampy. Yesterday I think I moved around too much, because I had muscle cramps. Today, I've got a headache, but really nothing else going on. Is this normal? I'm really trying my best not to freak out. It'd be so much better if I could go ahead and have an ultrasound, but I understand that there's really not much to see right now. Any advice on all this? Especially on how not to freak out?
