hi id say that for sôme women, back pain can be perfectly normal. search for symptoms of early pregnancy. whatever you do, dont worry-nothing worse for you or your baby x
To tell you the truth i honestly dont think you should be having back pain so early into pregnancy. I didnt find out that i was pregnant untill 7 weeks and didnt start experiencing back pain untill i was maybe about 5-6 months. hope this answers your question .
