Worried!

Br

Hi ladies, I’m on cycle day 30. I usually have a very regular cycle of 28 days, however my last cycle was 26 days which was very strange for me. I’m obviously late for AF and got a vvvfl from a FRER. I also got a weird tinge of blood this morning in some CM but absolutely nothing else. What has me so concerned is the excruciating back pain and sharp lower abdominal pain I’ve been getting. With my first baby, I received a blazing positive almost a week early and did have implant cramps so I know what they feel like. These pains are more of a stabbing pain. Does this sound like the beginning of an ectopic pregnancy? I’m so scared! I’ll be scheduling an appointment ASAP but hoping some of you can ease my nerves until I’m seen next week
