birth control

so i got the implant about 1/2 years ago and i recently switch out on it and got the IUD and it’s been trouble having sex with my boyfriend. he can feel the string and he say it hurts and with me, im always getting cramps. i’ve been breaking out a lot more. so i don’t know if i should just go back to the implant or do the shot.

i have a appointment today at 2pm so i just need a little advice orrr the pill.
