What are the chances ? 👶🏼

Long story short: my boyfriend came over the 9th at night and ended up having sex around 12 something.

I’ve always been a bit shy but that night I took over and I got on top and rode his dick and he always pulls out, but when he told me to get off I pinned him down (he enjoyed that lmao) and said it felt good and I wasn’t gonna stop so he came inside me.

After that we had sex 4 times/4 rounds but he only came inside me 3 times which I’ve heard that the first time is the one that “matters”. The last time he came I wanna say it was about 2/3am

I’ve been a bit anxious think “what if I am” or “what if I’m not”. I’ve been wanting to take a test but it’s to soon I rather wait the 2 weeks (my heart is gonna shatter if that test comes out negative)

My discharge has been watery.... for these past days

I really wanna know y’alls opinion or experience because I’ve heard that you can get pregnant right after period
