Provera

I took Provera to start my cycle so I can start my fertility medication. I had actually had a cycle on my own in February before I started the medication but before starting I had intercourse before and right after my ovulation window. Fast forward, I have took the last of the Provera on the 10th and still no cycle. The last few days my breast has been very tender to the touch and nipples sting. I mean any sort of movement it’s tender. I’m wondering if there’s a possibility I might be pregnant. Have anyone else took Provera and never had a cycle afterwards and it was a false alarm?
