Condom broke again & still unsure of birth control

So me and my boyfriend recently decided to have sex , our 1st time we had sex the condom broke. But he didnt cum in me and everything seemed to be fine but the next day I felt like shit but I was re assured things would work out. We did it other times...

and the condom was fine , just recently we had sex and the condom broke when he pulled out. He never cums in me and said he never will. He even got new condoms to make sure this doesnt happen , but it still keeps on happening. Im not on birthcontrole yet because whenever I take it , it ends up messing up my body and I end up getting really sick : ( does anyone have any advice about birth control and what he could be doing wrong with this whole condom brakage thing ?

It might be too small.
You need to leave enough room at the tip so there is enough room for him to cum and it won't break.
Talk to your doctor about diff. forms of birth control. It may be the specific kind and she may perscribe you on something else.
Yea, talking to your doctor is the best bet.
Don't have sex again until you do. Just to be sure.
