I am currently on the mimi pill (progesterone only) but my period is now 3 days late. I have been on this pill for almost 2 years now and have never been late. I had sex with my husband in the middle of my cycle but he pulled out just to be extra precautions. My question is do you think I could be pregnant?

I take my pill every day at the same time and have never missed it. I have had some nausea lately and tender breasts but thats also pms symptoms for me. My last period was June 29th and I usually have 30ish day cycles.

So what do you think?
