Tell doctor that you are pregnant and ask for some rash cream, or apply aloe vera gel. As for the cramping and lower back pain, I don't know how severe it is. If mild, then should be nothing la. If severe or accompanied by spotting, get advise from gynae. From own experience, I think got some mild ache here and there. Only in 3rd trimester backache was worse as baby is bigger. I bought a pregnancy pillow for support when sleeping at night.
Different people have different pregnancy journey. Not everyone will have morning sickness, I didn't have one.
