Cramping

So I had my D&C back in June.. cycles have been a little longer than they were I was always a 28 day person now I average 31-34 days which my OB said was fine. We’ve been ttc since and have had no luck so she took my progesterone levels and they were low so I have to take them from CD 16-28 every month. Well this month was the first time taking them and from the moment I started taking them I got awful cramps... then AF came and went and came off the progesterone after day 28 like I was told to.. I did get a BFN I checked before I stopped taking them.. but even before AF, during AF and now even a week later I’m still getting cramps it’s mostly on the left side and they won’t go away. It’s not so bad that I’m in excruciating pain or anything but it’s not normal for sure. I called my OB and all she said was that as long as they’re not so bad that I can’t walk or do anything to not worry about it.. but now that they’re not going away I’m starting to get worried.. anyone have any ideas? I was thinking about making an appt with her anyway. They definitely can’t be ovulation pains for 6 weeks now that would just be ridiculous
