Switch methods.  There's dozens of choices including nonhormonal methods if you're one of the unlucky women who reacts to all of the hormonal ones with behavioral issues.  And condoms remain a valid option even for married couples.

I tried taking bc after having my baby but it also made me angry and aggressive & very emotional so I discontinued. Idk either use condoms or just don’t have sex ; people still get pregnant on bc sometimes anyways

Make an appointment with your ob/gyn, sexual health clinic, or whoever does birth control where you live.  Finding the right method is trial and error not to mention time consuming as it takes time to adjust to a pill and determine whether it's just an adjustment phase or something completely incompatible.  There are different types of birth control pills and even within types there are differences between brands.  Anyone who gets it right the first time are lucky or they have low expectations and put up with more side effects than they ought to (beware the ones that kill libido stone cold dead).  Some women find the vaginal ring (nuvaring) has fewer side effects than oral contraception.  If you and your healthcare practitioner can't find a hormonal contraception that works for you consider the non-hormonal copper IUD. Make sure you carefully research the pros and cons.  Like the pill it varies how women get along with it.  For some it's the best thing ever, for others not so much so.

Make sure you keep the lines of communication open with your husband.  Most men are totally clueless about female contraception and think it doesn't have any effect except for preventing pregnancy.  The ONLY reason there isn't a male pill on the market is because the side effects are deemed unacceptable to males but they are the same side effects women have been expected to put up with for the past sixty years.  It makes me so cross.  Good luck finding a method that works for you.

Call your Ob/Gyn and discuss options.  There are dozens of different formulations of birth control pills, you may find that a different formulation will work better for you.

Also, just like millions of other women, you can do any or all of the following:

1. Use a condom and spermicide when you have sex.

2. Chart your ovulation and abstain from sex during your fertility window.

3. Use an IUD 

 Maybe you're better off speaking to your family doctor zx

Is the BC you're using high androgen? Some are, some aren't, but forms of BC with higher androgen indexes can have some unpleasant side effects for some people (like mood swings, acne, weight gain, hair loss). I mostly used BC as part of fertility treatment protocols, but my short stints with Nuvaring (a high androgen form of BC) made me SO short-tempered and moody, like I was PMSing 24/7. We called it "Nuva-rage." Comparatively, when I was on Desogen, I noticed no mood differences at all. Desogen is one of the lowest androgen forms of BC. The Mirena IUD is also high androgen, and after my first baby I had the thing in for less than a year before having it removed due to mood and weight-related side effects.

What kind of birth control are you using?

Speak to your doctor about alternatives. 

I think the issue is you not your birth control!! Talk to your doctor about your anger issues, change the birth control if you truly believe it’s that, many options are available, like my copper coil for example it has no hormones in so I’m happy with that, I got it all fitted the same day I asked about it

Talk to the doctor about the side effects and ask to try a different birth control.

If you are on something that can't be changed immediately - like the depo shot - then you'll need to ride out the symptoms until you are due for another shot and then ask for something different.

There are different formulas of birth control pills.  If you talk to your doctor about how this one seems to be making you very moody and easily angered, he can try a different formula for you.

It is usually best to finish the pack of pills you are on and then start the new pack when a new pack of the old pill would have started.

BTW - many woman have side effects for the first few months (usually two or three) of starting birth control and when their body adjusts, the symptoms usually get better.  But if you don't want to wait to see if that happens for you - you should certainly discuss these side effects with  your doctor.
