Need advice so confused

Okay this is gonna be kinda long. I had an ectopic pregnancy on or around October 12th I wanna say. That whole week just blurs together for me honestly. It was rough. I didn’t have to have surgery and it had not ruptured. Thankfully it was caught very early. I was only 4/5 weeks. They gave me my dose of methotrexate and checked my hcg levels weekly until they were at 0. It didn’t take very long to go down to 0. I got a terrible, terrible, awful feeling period on October 20th. It lasted 2/3 days which is normal for me. I believe my cycles are usually between 26-28 days. Since I switched from pregnant back to not on glow it hasn’t given me an updated period prediction. All it’s told me are the days I’m expected to be most fertile and ovulate. Doctor told my boyfriend and I it’d probably be best to give it two cycles before trying to get pregnant again...but we weren’t very careful at all. Today is day 29 since my last period however but have gotten negative pregnancy tests. when I found out I was pregnant (with the ectopic) I had a positive test the day of my missed period. So I’m not really sure what’s going on. It’s probably just my body still a little out of whack right? Anyone have any ideas?
