I'm 36 weeks 1 day and I've been having sharp pains in my behind and my lower back for the last hour, I'm not sure if it's from baby starting to engage or hes just lower now but having these pains since yesterday, I tried calling my labour ward but there was no answer.. they come for a few seconds and then go.. I'm a ftm so I'm not sure what to expect, also have been taking RLT since yesterday also..
