Pregnant or nah?

I got my nexplanon inserted in June and just got it taken out on March 20 (Tuesday). My husband and I had unprotected sex that evening after getting it taken out. Afterwards I looked at my period tracker and my ovulation day was March 19th (the day before the unprotected sex and nexplanon removal). March 20 was the last day of fertility during this months cycle.

I’ve read that some women are more fertile right when the birth control is removed, and I know every body is different and I don’t know how fertile I am in the first place (I’m 23, no kids, and have never TTC).

I feel some light cramping which is abnormal. Could be cause the birth control is out and my body is resetting itself, could be one of the first signs of pregnancy?..

Thoughts or experiences please!
