Birth control and missed periods

Cole95

Hi all! Need some tips on this. After having laparoscopic surgery my OB/GYN said it will be best to avoid getting my period for the time period due to terrible pain. So I have been taking Lo Loestrine FE at the lowest dose. He told me to skip the placebo pills and go right to next pack. My boyfriend and I always double up on protection by wearing a condom, but can’t help but freak out that I haven’t had my period in 2 months. I’ve taken tests they have been all negative and I had a routine ultrasound done after surgery and they never said anything was going on there. Has anyone else been told to do this? How did you deal with this? Buying tests can be expensive. Any tips would be helpful! Also have been diagnosed with endometriosis.
