BFP symptoms or post pill symptoms?

Taylor

I am approximately 7 DPO and the other night i has cramps so bad that it woke me up. The cramps lasted less than an hour but were intense. I was on the pill until November but never had bad period cramps (just mild) before getting on the pill. I had sex 2 times during my fertile window, about day 2 and 4. My nipples are also extremely sore...not my whole boob, just the nipples. I had mild cramps on and off yesterday too. Are these symptoms common after getting off the pill? Or are these symptoms that happened to you ladies before getting your BFP? I’ll be testing probably Wednesday (3 days before my expected period).
