3 days late..

Well my period is three days late and no sign of it coming. I obviously use this app to follow my period and cycles, and my period is seldomly irregular. We had sex two of my fertile days and on the ovulation day (according to the app), and hebwas fully aware of the situation because we avoid having sex during my ovulation but not this time. The only issues i have are my boobs hurt really bad and very occasional cramping. Im a little nauseated..🤔. Am i just being paranoid? I know no one can give me an actual answer but i cant stop thinking about it and I am not sure how else to distract myself. I had a miscarriage last summer and I am scared of it happening again too. My husband isn’t ready for us to have a baby and he is not wrong, we need time for our relationship still but now I am not so sure we have a choice, because I don’t want an abortion. 😓😪 And i think it’s likely that I am.
