HELP PLEASE. ANSWER ME PLEASE

Anne
Me and my bf never had sex. One day (30 th May) we were having more intimate contacts and he put his d next to my vagina and I didn't even feel any precum, he only touched the corners of my vagina. There was no penetration and no ejaculation for sure. Is it possible that even outside the vagina the precum can get a girl pregnant without penetration?
I don't know if I was in my fertile period or not ( even tough I know cm was like egg and with very amount in 5th June) and 3 days after the contact I saw a light red spotting and then a dark red spotting. I normally have that type of spotting before the period.
Can I be pregnant?
Ps. Now my cm is very dry
