Rosengård took an early lead through Olivia Schough, but just before the break the home team turned things around.
Matilda Vinberg hit a post that Thea Sörbo steered in and just over a minute later it was time again. Then through another post, this time from Sörbo himself, and inside the penalty area was Madelen Janogy who raked in the lead goal for the home team.
But the visitors came back after Emma Jansson nodded in a free-kick finish from Schough.
"Sour of course"
Then the Swedish national team player himself would get a golden opportunity to decide the match – in extra time. She was awarded a penalty after Olivia Holdt was brought down in the penalty area.
However, Schough burned the penalty against Bajen goalkeeper Anna Tamminen and the match ended 2-2.
"I was going to put it in the middle because I've never done that. So I thought she wouldn't be able to read it, but she was slow to throw herself away so then it turned out as it was, she says to SVT Sport.
After a heavy start to the season, Rosengård is still in the middle of the table.
"Sour, of course. We need all the points we can get. Our position would have been better if we had taken three points.
Will you try the same punishment again?
"I probably will, but then I'll make it better.
Big Hammarby miss: "Shocked"
Hammarby's Kyra Cooney-Cross also fretted after the match after missing a golden clearance. She came at high speed and fired the shot already outside the penalty area.
"Honestly, I was shocked afterwards. I couldn't believe I missed that moment. I thought about it the rest of the half," she told SVT Sport.
