Mother wants me to be on BC even though I'm married

Megan
So Idk what to do....I've been having problems with my periods and ttc. Right now I have to take a pill to start my period because I haven't had it for 3 months and I'm not pregnant. I've discussed this with my mom because she's a nurse and I wanted to talk to someone since I don't have a lot of close friends to talk to. Well I was telling her this and she was like " you better make sure you get on BC after you regulate your periods because it's to soon for you to have a baby" I didn't say anything and just changed the subject. (Me and my husband have been married since this past July ) I don't want to take any pills since we have been trying and I feel like we are gonna have a hard time getting pregnant in the first place since my periods have been irregular and everyone on my husband's side have had a hard time conceiving in general. Idk what I should say to my mom if she says this again .
