HSG and Cycle Changes

Emily
Hello, my first time posting. I had an HSG done in March. Prior to that my cycles were regularly 30 days, but had some other things going on during them. We've been TTC for almost 8 years, the entire time we've been married. After the HSG, blood work, his analysis we fall into the category of unexplained infertility ....which is both good and bad as it's frustrating to TTC for that amount of time with no real explanation. When they did the HSG there were no blockages, everything was clear. In April I was a few days late and now this month I was a crushing 7 days late and AF showed tonight. I had read a lot of women that got preg after having an HSG so obviously my hopes have been high but with the late cycles it has really taken a toll on me. Anyone who has had an HSG can you shed some light on how your cycle changed if at all after having one. Thanks.
