My period is irregular and took medicine to regulazied it couple of months back. My husband and i planned and tried to concieve naturally since from the begining of this year. But its dissapointing us every time we took pregnancy test. We had done medical test and there is no specific problem in me and my husband. My doctor suggested us to do IUI treatment to conceive and we had done it in begining of last month. I had light color and flow of bleeding for only days aroung my period time, but thought it was spotting and hope for kindof implantation bleeding. But my home pregnancy test this morning dissappointed us again.Please suggest me.
