In need of some knowledge/advice ladies 🤨😊

Me

So ladies I came of the mini contraceptive pill 7 weeks and had a period 6 weeks later so 10/11- 15/11 now we were actively trying before , I had unprotected intercourse at one point in it and once last night bout 7 pm but I’ve been up since about 8 am with cramps on the right side and in the back , could it be linked with last nights intercourse or the intercourse during period ?
