Is It a Trap?

So I have two boys he has a total of 4 kids my second child is by him (my Fiancé) I always talked about trying for a girl BUT In five years I’m not on birth control due to the birth control causing me to have major side affects (health issues) but I also wasn’t expecting to get pregnant either so... my question if I WERE To get pregnant would that be considered a trap? Bc I know for a fact he would want me to have an abortion Bc we don’t “need” anymore right now (his words) if it wrong if I “were” to be pregnant and don’t say anything Bc Im NOT GETTING A Abortion THATS Totally Out ...p.s we lost twins in June of 2019 and I’m more so scared that might happen again
