Okay so my periods were regular from the age of 13 to 17. At 17 my periods became so irregular is was ridiculous. I went months and months without a period at a time. I'm 21 years old now. My last full period started between November 13-14. My periods are still irregular. But have been getting them every other month or so. My period lasted until the 21st. I was sexually active with my fiancé on November 29th (unprotected) but did not have sex until climax. Same with December 5th. I have not been sexually active with him since. This past Saturday I started feeling cramps and noticed no blood in my underwear but when I wiped there was blood. (Not pink, just red as if I would have started my period). Sunday when I woke up a panty liner had some blood but nothing heavy. It stopped around 5pm. I have not had anything since. I am not nauseous nor are my breasts sore in anyway. I have taken two pregnancy tests. One I took the 24th of December and one yesterday morning. Both negative. I still have slight cramping. I also took an ovulation test and it had a solid pink line and a light faded line (so I don't know if it was positive or not). I know there is a possibility I could be pregnant. Does this sound normal?!Any input would be appreciated!
