Cycle questions

I had an ectopic pregnancy back in March and my surgery was on March 21st. I was 11 weeks. My hCG levels went down & I started trying again. My cycles usually last 30-33 days. On cycle day 14/15/16 I got a positive ovulation test. The test line was as dark as the control line. Then, my line faded away & Ovulation was some. On cycle day 20/21/22 it was darker than the control line. Now my period is expected to be here tomorrow. I usually have cramping about a week before my period but I have no cramping at all. The only thing I do notice is a weird pain type of thing will go from one side to the other side but like I said, I just got surgery so things are different. If anyone has any ideas just drop a comment, thank you!!
