Worried/ periods / pregnancy

Dshelle

So I had unprotected sex for three weeks and my next period supposed to start October 10 or the 8th I feel like I’m not going to get my period on time due to having a irregular period sometimes I feel like it might not come at all or come the week later or couples days later. I hate having irregular periods Bc I have to wait for a whole month to see if I’m pregnant or not.

Have that happen to anyone else in the same boat? If so what can I do or any advice? I’m on dpo4 on flo app but dpo 10 on the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>.

Haven’t took no test yet last time having sex was September 30th from the September 9th -30th
