Consider going to a gyn physician/clinic to be examined & check your blood pressure, also to review your history, then you can decide what contraception is appropriate for you.

Stay safe,

Good idea. The number 1 cause of pregnancy is having sex. Number 2 is having sex without contraception. Number 3 is having sex with the wrong contraception or one you don't use properly. Go see your doctor or GYN practitioner to get started on the contraceptive that is right for you.

Use something long acting and you don’t have to take it everyday like a subdermal implant in your arm, has low dose progesterone, good for 3 years and 99% effective. You’ll notice irregular bleeding for first 3-6 months, usually settles down after that and you might have no periods until you have the device in your arm. Look up information on Nexplanon.com
Take care and stay safe!
