Hi am expecting my period on Monday 17th aug which had me at 11dpo.. symptoms going to the bathroom more than usual.. eating all the time.. my bbt this morning is 36.8 cervix high soft and closed I check it everyday.. The most problem I have is the worst lower back pain ever going on for like a week now.. My hubby  said I should check at the doctor.. am bawling my eyes out everyday but don't know why.. pregnancy text so far negative.. I don't know what to do.. I know you guys are no doctors here but just a little advice would be appreciated if should go see a doc about the back pain it hurts even if I moved ??
