I have been getting so many mixed signals and I don't know what to do. I haven't gotten a period in 6 months so I took one round of provera and everything went smoothly. I had a positive OPK on the day Glow had predicted and i started getting what I though were early symptoms: headaches, breast tenderness, slightly nauseous, very mild cramping, swollen gums and a light pink CM. I took a test at 9 DPO and got a BFN. I waited a few more days to see if my period would show up at 13 DPO and nothing but one pink spot around noon, not enough for any protection. This happened again on 14 and 15 DPO and now nothing. I tested again on 15 DPO and another BFN, but I am still have breast pain near my armpits on both sides, erect nipples and heavy feeling in my lower abdomen. I'm going to test again on 18 DPO, but not sure what to do next. Has anyone else had a similar situation?
