I had a hsg done in Jan and found out i had two blocke tubes, but the dye opened one of them up. I ovulated that month using the ovulation kit and didn't get pregnant. In feb 4 I had a period and i used clomid on days 5-9 and ovulated on day 17. Now it's March 5 and no period and negative test. my cycle is usually 26-28 days. I had cramping around the time my period was suppose to come for a few days but no period. my hpt was negative could i still be pregnant
