What's going on? HELP

My partner and I have been trying to conceive for the last 9 months. I have been monitoring my cycle but haven't really got anywhere.

This 3rd of September I took an clearblue opk and I got the smiley face.

The next day I took another opk and it had low surge.

Then later that night I get a sharp pain in my right side and it was there the next morning so painful I couldn't walk. I went to the doctor and she said I had an ovarian cyst burst but she said that would explain the sharp pain. It disappeared later that day.

These past few days I've been feeling extremely tired, I'm sleeping nearly all day. Sore boobs and they feel really heavy, feeling nauseous and sick, severe cramping, bloating, really hungry.

I did a pregnancy test a few days ago but I'm pretty sure it was negative but I swore I could still see a line that no one else could.

My period is due on Monday.

Was just wondering if anyone else had a similar thing happen to them.

Needing some advice.
