infertility issues & dealing with best friend

I hope this is the right place to put this if it’s not please advise...

I need some advice on how to handle a situation that’s really bothering me. Here is a little background... Me and my husband have been TTC for (almost) two full years. November 1 (2019) we started seeing a fertility specialist getting every test done under the sun... just at the beginning of this year we found out that my husband sperm is likely the reason we are having so much trouble. Next month we will be starting

IUI .. then if that doesn’t work IVF

Now I’ve kept this journey very private and have only talk to my best friend, my mother and my brother about all the testing we’ve been doing & all the struggles we have had in the last couple years... unless you’ve dealt with a similar situation it’s hard for anyone to really understand what you’re going through so it’s easier just to keep it to yourself sometimes. Well my best friend who has complained about her boyfriend for quite sometime now, about how lazy he is, how he doesn’t take care of himself.. and lots of other things has been texting me every day for the last week telling me she thinks she’s pregnant and her symptoms etc. They haven’t been planning this & quite frankly probably shouldn’t have a baby at this time (but that’s besides the point). Her period is due today... instead of just waiting until she knows for sure if she’s pregnant or not she chooses to talk to me about this so casually without thinking about how it possibly makes me feel right now after finding out our news. Not to mention... she sent me a screenshot of one of our old friends baby announcements and said “There’s NO way i can be pregnant at the same time as that psycho”.

She also sent me a picture of her drinking last night... like I’m confused if you really thought you were pregnant why would you be drinking?

Like what is going on with my friend...

Now before anyone gets all upset with me... I get it that’s what best friends are for but it’s almost like she’s either completely oblivious to how I’m truly feeling or just really doesn’t think it’s a big deal. I’ve told her multiple times in the last couple days to just take a pregnancy test yet she just keeps putting it off and talking about it. 

Please keep your unhelpful comments to yourself. I know I’m not the only person in this friendship and it’s probably difficult to grasp the whole situation just by me telling you a few things but if you have any advice on how to handle this situation.... Please let me know.
