Stressing about possible Pregnancy

For some background information, I have a child from a previous relationship that I’ve been taking care of as a single mother.

My current relationship has lasted about a year. Last week, we had unprotected sex (very smart I know) and we were both pretty drunk. I’m not on birth control so once we were done I asked him if he had finished inside me in which his face changed and he said “I think so, I don’t know”

Because of this I let it go, according to glow I’m not anywhere near my ovulation time, so I just counted on that. We had unprotected sex two more times over the past two weeks, but the first time according to him is “the most concerning”

So, the other day he offered to buy me the pill. I agreed and I took it, but nothing happened. However, it has been more than 6 days since that first day we had sex so it’s pretty much ineffective at that point.

With my first child, I immediately felt sick after I got pregnant. Almost like the flu. I’m now feeling the same way, along with breast tenderness and just over all feeling like crap.

I told my boyfriend and now he’s excited, which honestly explains why he offered to buy the pill 7 days later, because it’s pretty much ineffective. He is taking about how happy his parents especially his mother will be if I’m pregnant.

I, however am stressing and scared shitless. Even though glow says I wasn’t ovulating, we still had unprotected sex, and there’s still a chance I’m pregnant and I don’t know what to do.

Should I stop worrying about it since it wasn’t my ovulation time? Or should I stop ignoring my symptoms and count on taking a pregnancy test. My boyfriend is extremely supportive and happy, but I’m very nervous. What should I do :(
