Hi everyone, I am so confused and stressed at the moment. I had my contraceptive implant removed about 2 and a half weeks ago. The day after I had it removed, I had a bit of red blood, then after that for a week I had brown blood. It wasn't very heavy . It's been about 3 or 4 days since I have been experiencing cramping, lower back pain and white clear discharge whenever I go to the toilet. I have taken two pregnancy tests, one at home and one at my local walk in centre. They both were negative. The doctors aren't very helpful, as I didn't get much of an answer from them. My OH thinks it could be false negatives,as it could be too early to detect the pregnancy. Plus the cramps are unbearable. I'm just wondering whether it's my body adjusting, after the implant has been removed. Even though, it doesn't make sense why I would be having pregnancy symptoms . I also wasn't told that this happens after having it removed. So I'm so unsure of what's going on. Before any one asks, I'm not imagining the symptoms, they really are there!🙈

TIA
