I was on birthcontrol (implanon) and had it removed the 26th of June. I have had intercorse with my boyfriend twice a week ago. Then on Wednesday I wiped and there was 2 dots of blood and nothing since, I've been eating really weird foods, nausea every once in awhile, my senses are hightened by just a bit, my boobs are tingly, the areola is looking a bit darker then normal and they're perky almost 24/7 also with some mild cramping here and there and just last night I was having llight brown discharge. What could this mean? I've been checked for an STD/STI and I'm clean. I took 4 pregnancy test (urine) and they've come up negative but I'm due for a blood test this week.
