Pregnant?

[Lydia_97]

Hi,
   I'm a female 21yrs old. I'm 5'5 and weigh close to or either 300lbs. I got super drunk one night and made bad decisions and ended up having unprotected sex with a guy. I have the birth control Nexplanon. I got it inserted in June of 2015 , the summer before I went to college. I'm now a junior in college and will be needing a new implant this summer in June. I read in several articles online that Nexplanon may not be as effective in overweight women/it runs out quicker so I may not be fully protected. Does anyone have any information on this? Is there a chance I could be pregnant? Did my Nexplanon run out? Does my weight affected it that much? Please help! Thanks so much!

Hi.  Your weight may impact ovulation in general.  Sometimes women don't ovulate when weight is too far outside of normal.  Do you get regular periods?  When is your next period due?

HI! sorry for responding so late! With my nexplanon implant my periods are irregular so I'm never really sure. Sometimes they're on schedule and other times they aren't. I had two last month but the second one was super short and I'm worried it might just be implantation bleeding. I've been on Nexplanon for 3 years and was researching online and learned that it may not be as effective in overweight women. My BMI is 44.8 which is morbidly obese and I was just wondering how likely it is i am pregnant. I know it lasts up to 3 years in the US but it said that overweight women might need to get it taken out sooner. im not due for it to be taken out until June, but I wasn't sure if it should have already been taken out
