So my last period was July 16th. Calculating that to now I would be 6 weeks prego. My periods are regular

I had surgery on August 16th I had a breast augmentation.

I ovulated around July 30th - August 5. Yes I had sex multiple times in that time period. No protection.

So on August 16th the day of surgery my period was “scheduled” to come. I track them. I put off as the anesthesia slows the body down and does other things. I’ve been constipated for example. But it shouldn’t be continuing 2 weeks after surgery. I don’t know what to think because I’ve been putting it all off thinking from surgery to the meds I was taking after surgery.

I have been cramping ever since surgery.

TODAY though, I am having extremely bad cramping. In my back, and radiating into my legs, even kind of uncomfortable to walk. I took a pregnancy test last week it came up negative haven’t taken one since. Taking another test today at some point.

What do u guys think??
