I feel crazy.

Brief history-- was on birth control however I am super sensitive to hormone changes so the last time I went to get a refill the pharmacy had changed the pill and I got really sick again. So DH and I said enough is enough and I went off them. We decided to do NFP and I began charting. First cycle (July 21,2017) we didn't have intercourse at all and it was textbook with the changes in mucus. Then this months cycle started on 8/15. I decided that I was going to see if I was right in my charting and so I did OPKs along with me checking CM. Had changes in CM but nothing like the previous month. I still noted two scant EWCM days but all my OPKs were negative. Some were darker than others but never full on positive. So I was a little disappointed. Then maybe a week later my breasts started to hurt, nausea, cramping, craving milk, and that horrible metallic taste in my mouth that I could not get to go away. I started taking HPTs embarrassingly early and all were BFN. So now here I am - AF was due yesterday and still hasn't shown her horrible face however I feel like I am about to start. I took an opk this morning since I refuse to buy anymore HPTs until next week but needed to feel like I was doing SOMETHING and it was almost as dark as when I tested when I thought I would've ovulated. My docs office was zero help and said to "keep trying". However i feel crazy like I'm making these symptoms happen and making my period late and I'm clearly not pregnant. I sure hope I'm not the only one. I'm just ready to get this next show on the road.
