i guess you could say we've been trying for a few months now to get pregnant. my periods are very irregular because of the depo shot i got it January. i only got the shot once and since then my periods have been anywhere from bleeding for a whole month to having 2 periods a month. my periods have started to get regular in august and i only had one then. on september 6-12 i had my period. but on september 18-22 i also bled. we have unprotected sex as often as we can. on my app it says i'm 5 days late. is there a chance i could be pregnant? should i wait until the end of this month to see if i do get my period before taking a test?
