Possible Pregnancy? Infection? -Update-

Hello, I had unprotected sex at least 6-8 times within 5 days, it started on ma Tuesday he pulled out every time. On Tuesday we had sex he pulled out but i felt his cum drip down, Thursday he came inside so 3 days later I took a plan b. We then continued to have unprotected sex. With the withdrawal method. It’s been about two weeks and 3-4 days. My period is due in 5-6 days. I have been very sick like cold, nauseous, bloated and cramping. I am not one to get sick be nauseous or cramping. I have only had cramping twice around my period.

The day after he came in maybe it was a day could’ve been two or three I was having a lot of clear watery cm.

So lots of questions:

Could I be pregnant & it’s to early to tell?

Could I be sick?

Infection?

What is this?

Help, I really need to know to test if it’s worth it.

—————UPDATE————-

So all of that started happening 4 weeks ago, I took two pregnancy tests. Each of them a week apart and they both showed negative. The first one I figured it was to soon because it had only been a 1 and half to 2 weeks since we started having unprotected sex. The third week I still was having lots weird symptoms a lot of abdominal pain. So I thought maybe I had some sort of infection but no smelly discharge nothing so I assumed well maybe my period is coming early & im cramping which isn’t normal for me. So I took the second test and after three minutes it should negative.

I did notice that the first test right away within 30 seconds it showed negative. The second test definitely took 2-3 minutes before saying negative.

My period is expected in 5 days, we have continued using the withdrawal method.

Symptoms now :

Nausea

Hunger ( I crave everything for sweet to salty, could be period cravings)

Tight lower abdomen

Dark areas around nipples

Occasional sensitive boobs

Could there still be a chance of pregnancy? Or should I just wait for my period?
