HSG and AF question ?? Any opinions or advice ?? Thanks!

ki

I had my hsg done this cycle, AF arrived when expected but was really light and only lasted two days (so I thought!) AF stopped til the next morning then started back up heavy for about an hr then went really light again for about 2 hrs then stopped again, then today it happened again AF came out of no where again really heavy for about an hr and now I’m only spotting again. I’m sure it’s because of the hsg AF has been a little odd, but has anyone else experienced anything like this after their hsg ? I’ve read posts about no AF or a late AF after the hsg but none about a on and off AF. It’s been 5 days now, normally I only last about 4 days first day light 2-4 days heavy then back to light on the 5th day. Any advice or opinions would be helpful ! Thanks !
