Provera 10pills 10mg & TTC baby #2 (TMI)

Ja

So I took my last pill yesterday morning through the whole ten days of taking provera I only experience cramps most of the days I haven’t start spotting yet. But I GOT THIS MORNING!!!! i did had intercourse with my boyfriend Saturday and Monday unprotected which I wasn’t supposed to do if I did intercourses I was supposed to use protection stupid me. I haven’t had a period since September 2018 on the 6th -10th so I was prescribed provera to start a cycle I took so many pregnancy test they were negative. As this app say I’m CD132 & period is late by 103 days , & as right now having cramps that’s feels like contractions. what could this be ?

P.s

I’m coming off the depo shot since July 2018 but was taking BC pills (triNessa )July-August 2018 .
