Am I over reacting?? 😩😭 please read.

So my husband and I have been trying to have a baby for a year now. We've been referred to a fertility specialist and we're trying Clomid this month.

My best friend of 7 years (she's also my sister n law) just started dating a guy she just met 3 weeks ago and decides she needs to tell me that she isn't going on birth control and just wanted to warn me that it's a possibility that she could get pregnant. We talked about how pregnancy is 100% preventable and that I know how sex works and I didn't feel like I needed her to say that to me. Honestly it pissed me off and I let her know that. We didn't talk for a few days because I needed space.

A few days later I decided that it wasn't worth being so upset about and that we needed to talk about it. The first thing out of her mouth was that she went to her OBGYN and that the doctor said there was two lines and one was faint. I was honestly in shock and ask her what she meant and she said that the doctor told her that he doesn't think she's pregnant and to take a test in a week to make sure. He also told her that he wouldn't do a blood test now because it wasn't needed. Just a side note I'm a registered nurse who has worked in a doctors office and I know this isn't how things work. Two lines means pregnancy. There's no confusion about that. If it was questionable they would have done a blood test. She was very insensitive about the whole situation and acted like it wasn't a big deal that she could be pregnant. She's acting like she was trying to spare my feelings and that I'm over reacting and she's blaming me being emotional on me being on fertility medication.

I don't know if I'm over reacting but just writing it all out makes me even more mad. I honestly feel like she's making things up to hurt me or that she's trying to get pregnant on purpose. I really don't want anything to do with someone who purposely tries to hurt their friend/family.
