Unsure

Hi, me and my now ex boyfriend had a faulty condom that broke on us the last time we had sex which was about 2-3 weeks ago and he also admitted to finishing with thr condom that broke on us. But last week leading up to today I started getting super sick in the morning and getting dizzy when I tried to get up too fast. My period has also been four days late and I told him about what happened. He helped me pay for two tests and one came out like, broken? No line or anything and the other was a faint positive. I feel like it could be something like a pregnancy but both of us aren’t ready for a child cause we’re still young and need to finish school but I just want to know if I should still try and make an appointment with my doctor to find out for sure.

My period ended about a week before I had sex so when I checked it was during my ovulation period like the third or fourth day.

This is just a scary moment for me and I’m unsure of how I should approach this. Also today my boobs were super sore on and off and I don’t know if that could also be a symptom cause I’ve been very tired lately and little edgy when people talk to me.

This whole paragraph is all over the place I’m sorry I just need some options!
