Ok ladies 
​It's officially 33 days since my last period, my periods are always 28 days sometimes 37 days. I took hpt yesterday since my temps are still high and was a BFN. Yet till right now I have LOTS of sticky and screamy whit CM. I did take the hpt during the afternoon and I had drank a bit of water before it. Idk if my period is coming or if I am pregnant. What to you guys say ?
