weird cycles?

i first became sexually active the very end of september, my period was regular as it always has been in october and started becoming irregular in november, last month i was 10 days late (41 day cycle as opposed to my usual 29) the only forms of contraception we use are condoms and pulling out combined, i was terrified of being pregnant last month but eventually got my period and was relieved. this month the same thing is happening, my period was supposed to start yesterday and isn’t here, very sore boobs and occasional light cramping and brain zaps, but no period. i’m not sure if losing my virginity has affected my cycle or the stress of pregnancy scares had affected it? before this my periods were like clockwork and i could always count on it to come an exact day every month. i’m unable to get on birth control right now so condoms and pulling out are all we have.

so far im having this discharge and no period, a little nervous. is this normal or should i be worried? thank you
