What should I do?

I go back for my 6 week appt soon and I’m not sure what type of birth control option is best for me. We were TTC for 2 years before seeking help and then after a year of failed rounds of Femara and then a few rounds of Clomid, we got pregnant. I was highly irregular so I’m concerned about methods which prohibit periods. I’m worried when we’re ready for #2, we’ll have trouble like that again—did anyone else have issues like that?

I was briefly on a bc pill prior to TTC, and it made me insanely emotional and I gained a lot of weight so I stopped taking it. What type of bc should I use? I’m not against taking a pill every day, but I obviously don’t want to gain weight or get crazy emotional again.
