Hey guys, im jessica and new here. I have been having a problem. Ok for the past two month my af has been irregular. Its very light and only stays on for 2 days. I thought I was preggo but my doc gave me 3 preg tests and all negatives. But the thing that worries me is that my irregular periods started after I had "realtions" with this person. We've been together since october and my nov and dec periods aren't normal. Plus we didnt use protection but he pulled out before he came. I know this was dumb. im not on birth control. Plus I get this aching feeling in my stomach like I pulled a muscle, its just sore. Sometimes at the bottom of my stomach but mostly up by my rib cage. Cramps come and go but iam uncomfortable a lot lately laying on my stomach. Plus this time before my af my boobz got really sore I mean to the point if n-e one was in 5ft of me I was covering my chest which isnt normal for me. In november I use to get dizzy a lot like I would just be sitting and the room would start spinning. Sunday in the car I was getting nauseated and had to open a window. But other than that I dont get dizzy too much. Whatz wrong with me? If im not preggo what is this? Im nervous plz help. Responses truly appreciated :d
