I need some advice

Monica • 👼 you would have been loved

So on Monday 10/1 I got my BC removed (Nexplanon) though my boyfriend and I had sex the day prior, as I’m waiting in the room while the nurse is taking my information she told me that it’s possible I can become pregnant right away. Now I’ve been wanting a baby for a very long time to where my body has “tricked me” to thinking I was pregnant with all similar symptoms to pregnancy but I knew I wasn’t .. but back to the point as today 10/6 is my first fertile window we had sex but after I had pretty strong cramps and I’ve been feeling bloated and nauseous the past couple days and I also don’t start my period until 10/25 ish . Do you guys think it’s possible I could possibly be pregnant or am I overthinking things again 😣
