I have an interesting question for you all… I woke up yesterday morning with the most deep muscle pain in my bum (both sides) and top of legs. Felt like I had done a really heavy leg session in the gym (but hadn’t!!!). Also very slight back twinges like my sciatica is returning. I am on my TWW and period due in couple of days… not sure if this could be early pregnancy sign? Has anyone else had similar? Also had a pulling pain come and go past 2 days (but only on the left side). Could be / probably clutching at straws here… as usual I seem to have a different “symptom” every month and turns out to be BFN 
my husband is tired of hearing about it now. Been TTC #1 for nearly 1 year, and hoping this is our month but coming to terms with the fact this could be a long road for us….
