Thick Cervical mucus ?

Sami

Hey ladies so I’m a little confused, I’ve obviously had mucus before and all that, but this is month #2 that I haven’t been on birth control (had one injection of depo and never got it again). Me & my boyfriend have sex and he cums inside bc we’re trying to get pregnant, I haven’t had my period yet bc of the hormones from the birth control but I’ve noticed that my cervical mucus is getting very thick. What could it be ?? I just want to know every possible reason it could get thicker lol thank guys
