TTC: Confused

So I have been TTC for 7 months. We started seeing a doc cuz I wasn't cycling. Ended up finding cysts and husbands numbers were also low. We have been working towards an IUI, but haven't gotten to try due to cysts, etc. This last time it was due to follicles not growing fast enough. Well, we still were having sex on our own and changed hubby's diet. Well, 21 days after my period started we had sex, and now, eight days after that, I am cramping moderately in my lower stomach and experiencing more CM. I have a bbt of 98.2. Thoughts? Plan to take a test the 13th.
