In October I had genital to genital rubbing which was unprotected, he did not ejaculate on me or near me however there was pre-cum. I have came on my periods since every month however I have gained weight but been eating normally and more recently I have had flutter in my stomach and also can feel palipitations more like a pulse. I did do a HPT in Oct 3 weeks after the uncident and again in Nov both negative. I have extreme lower back pain and I am always tired.
