I'm not sure what's going on...

Hi ladies,

I'm having some trouble and I am worrying. I have always been regular with my periods. Before last month I always had a 29/30 day cycle and it was like clockwork. Last month we really got serious with baby making and my period was 10 days late. Obviously this got our hopes up but then AF arrived. During this 10 day period I got tested for infection as I was worrying on why tests were negative but my period wasnt coming. This month again, I am now 5 days late from what Glow predicted and I am on cycle day 38. I am having a lot of pale yellow CM. I am using ovulation sticks and my partner works away so when we had sex this month these sticks said I wasnt ovulating. Therefore, I'm not getting my hopes up at all but I am more worried about why my periods seem to be all over the place. I also have pain in my calf thats been occurring for a week whenever I lie down but I dont think this is related to anything. Ha ha. Please help?
