No, it is not normal to have the irregular bleeding that you mention on clomid. If I understand you correctly you had a D&C and lap after Feb15. If everything is normal, then you can resume treatment after checking a pregnancy test. You should have a baseline ultrasound cycle day 1, 2, 3 ,4 or 5 before you start the clomid. Also if clomid does not work (you are on a big dose of clomid) you may need to try another medication for ovulation induction like letrozole or injectables.
