Just want opinions

I’ll preface this by saying .. I know I need to test lol BUT my cycles have been pretty irregular since my daughter. I got on metformin a little while ago but I stopped because it really fucked my stomach up BAD . So my last three cycles have been closer and closer to the normal cycle timeframe of like 31 days, last cycle was 40. How long before your period do YOU PMS? I thought my cycle was coming because my ovaries have been hurting and I’ve been cramping , sore boobs . Normal stuff but it hasn’t come .

Me and my bf had unprotected sex two weeks ago . I dont want to buy a test if I don’t need to lol , how much longer should I wait ? Technically the app said I should start today but obviously it can come whenever and I don’t trust the app. Last time I got pregnant with my two year old , the app actually was right about ovulation but because my cycles are so weird I don’t think I could be , just my body fucking with me .

** Not trying but me and my bf are very stable so if we do conceive it’s okay and wanted either way .
