We have undergone the iui process on 11th feb. Now my wife suffering from little spotting of a brown or red color. Spotting occurs sometime and sometimes not. She is on progesterone 10 thrice a day, ecosprin 75 at night, and one multivitamin supplement. The iui doctor asked to do a home pregnancy test on 27th feb. Yesterday he scan her for a lining check, and he said the lining is fine. We check the home test at till now it's negative. Now, what are the causes of it, and how to treat it? Currently, my wife is 31 years old, and myself 34. We have previous 2 pregnancy histories one was a miscarriage at 10 weeks and one was an abortion at 3 months due to an omphalocele suggested in the scan. Before the iui process, we both have done hormone level tests, krotyping, and semen testing as the doctor suggested. All the reports are normal. Aborted baby karyotyping has also done that also normal. Interestingly, both these previous pregnancy spotting occur but after 6 weeks of pregnancy. At the time of iui process doctor has found some polystic but he is sure he treated that before to go iui process. Can you please guide us what to do ahead?
