I was on clomid for two cycles and ovulated with good progesterone on day 21 but did not get pregnant. I took this month off to let my body rest because my periods are really light and only last 1 day and never have to wear more than a panty liner. I am 35 years old and have no children. My last period was on the 7th and I have very strong cramps and thought I was gushing blood but I only had half of the tampon was saturated. I have been cramping on and off since then and it has been 12 days. My nipples also have been having spasms occasionaly and blue veins are prominent more than usual. I feel light headed at times and sometime nauseated or emotional but not very often. I took a pregnancy test a couple days after my period and it was negative. Do I have a cyst? Why have I been cramping and I never have sore breast mid month only sore nipples a few days before my periods. Please help.
