Ay alam ko yan, 37+6 weeks na kayo! Honestly, hindi lahat ng moms ay may visible discharge or signs bago maglabor, kaya normal lang yan, some of my mum friends didn't have any warning at all, biglang lang gutom or ligtas ang baby haha. Since you're already at 37+ weeks, I'd really suggest checking with your OB just to be sure everything's fine and get their take on your specific situation, kasi bawat pregnancy talaga ay different and they'll know best what's normal for you. Pag may doubts ka pa rin or feeling mo may off, don't hesitate to call your doctor, it's better to confirm na healthy kayo both.
