lately I have been grilling really irregular. thelast Time I was with anyone was on January 11. since then my last period was 9 days late, light to medium the first day, and the second was really heavy. only lasted 2 days. ( usually lasts about 4) I have been experiencing many pregnancy signs, including gaining about 20 pounds n the last month, I have weighed about 120-125 since I was 15 I'm now 23. & my first pregnancy, with my sin I didn't find out until I was 6 months, but with my next pregnancy, twins, a knew by the time I was about 4 weeks. that pregnancy didn't go full term. now with everything going on I'm not sure what to think or do. test results keep coming back negative.
