Nicole • PCOS•TTC 3 years
So as of today I am 20 days late. It was has been 6 days since I took a test. Today and 6 days ago I had EWCM, but negative ovulation tests. Get off and on cramps, but not as bad as PMS cramps. Also my upper right side is hurting. Has been hurting over a week, but more noticeable today. Anyone experi3nce anything like this?!
