You say your doing better , first sentence.

Then

Last bit is her again wanting to get pregnant ?

So ummmm how are things better????

If she’s on the pill you need to physically watch her swallow it each day. Because if not she will get pregnant regardless of your wanting to wait, since she basically told you she only wants sex while ovulating because HELLO that’s when a woman is able to get pregnant.

Please google to read facts about when a woman can get pregnant.
