TTC WITH PCOS

I was diagnosed in 2016 with PCOS. November of 2017, my husband and I have been TTC.

I took a test March 6th and it was negative, but I’ve been having so much heartburn, headaches, really weird mood swings where I don’t want to eat either. I feel sadder but I don’t know where this is coming from. Every time I feel something with my body I google it and of course the first two “pregnancy” and “menstrual cycle”, my period was supposed to be last week. If/when I get my period(because it’s so irregular) I get it the same time as my mom and friend, they both got theirs last week.

With pregnancy tests being so expensive, should I wait???? And how much longer should I wait?

Any advice?
