I need advice

Okay so I been trying for baby #3 since I got the nexplon out in June. I started to try for baby #3 in July and so far no baby . It is November 2019 . On October 1st & October 4th I did the “BD” and then had a period on October 17th-October 20th

Then had baby dance again on October 25th 2019 I have had cramps 2 weeks ago . Felt like I was gonna start my period today but nothing. My period is due around November 13th . I know every pregnancy is different so anyways I been moody and cranky with my 2 kids especially them :( not trying to be. I been cranky and stressed to their dad also .

I sometimes get nausea and that’s it . Is there a chance I could be pregnant with the 3rd baby ! I wanna test but don’t wanna get my hopes up like I been doing for the other months . I have 2 days left until my period is supposed to be here and it usually comes way before it is supposed to be here and not a damn thing .
