Around april 10th, I had sex with my boyfriend. It was unprotected but we only spent about 2 minutes or less having sex. He assured me that no precum had came out because he would have been able to have felt it. When he did pull out, pre cum did appear about 30 seconds later. About 1-2 weeks later, we had unprotected again. This time it lasted for about 5-7 minutes. It was not continuous because he kept pulling out, not because he pre-cummed. Again he assured me that no pre-cum had come out. Around the last week of april to the beginning of may, we had protected sex. Now I am about a week late on my period. Sometimes I am erratic with my period. My last period (beginning of april) was a couple of days late. But now I am worried because it is almost a week. Can it be a coincidence that i've had sex and that i'm late on my period? Or am I definitely pregnant?

Should I get tested by using the home pregnancy test?

I have not been feeling sick or nauseous. I haven't been experiencing any pregnancy symptoms. However I am still worried that I might be pregnant.

I read online that many things can cause your period to be late: stress, medication. I have been taking different kinds of medication because of my allergies. Does this have anything effect on my period?

Also, is it true that a guy can feel whether his pre-cum comes out?

Someone please respond because i'm very worried.

Thank you.
