So March 11th is my first appointment.

I went to the DR. Last tuesday over not being able to hold down my food, constantly throwing everything back up. They said my Bloodtest came out positive of me being pregnant but not my urine test, so the next day I took a test and it came out a faint line. I waited another week and it came out darker, Are faint lines a sign of early pregnancy? Or is it a sign of something bad? I havent had a period in both months of Jan and Feb but had it at the end of December, My ex and I didnt have sex for two weeks during and broke up on january 7th. I started seeing a guy ive known for a while around Feb 4+5 from the 11-16th. We of course, had intercourse, he did pull out every time. But Is it possible that it could also be my exes even though I was on my period and we didnt do anything, maybe something from before? I have PCOS so my period are all over the place and I have been stressing hardcore over life, so I figured missing januarys period was because of that.

Im just concerned about having a low HCG and if it could mean serious harm to me or the baby.
