Help me please.

I’ve been on the combination pill for 5 months now.

So awhile back i left my birth control in a car in 20 degree weather for a couple of hours during a concert.

When i came back I realized that the packet said for it to be stored at 68 degrees, lowest. I googled. Saw some people saying that it’s no big deal and that the cold doesn’t effect birth control. So i looked at the packaging, no condensation. no tears. nothing was powdery. so i thought they were fine.

So I continued the packet, my boyfriend and i had sex where he came inside me around two days ago.

and today i got stretchy egg white, clear cm.

and i checked my basal temperature, and it’s 99.2.

I thought the combo pill stopped ovulation.

Am I ovulating??

Did the cold do something to the pills to make them ineffective.

If not then why is all this happening?
