Hey, I really need your help.

I came off the jab on March the 10th and have been having unprotected sex. On the 8th of April, I got my period and it ended on the 14th of April.
I since have had unprotected sex on the 15th, 16th, 17th, and 19th of April. I haven’t taken a pregnancy test yet but I have had some kind of side effects like cramps in my tummy, really sore breasts that have gone really hard even around my nipples, it feels like a round ball inside my nipples, I’ve been really tired since sleeping twice a day. Feeling sick in the morning not wanting to eat and sometimes getting it throughout the day. I have had a whole lot of discharge and a bit of spotting and lower back pains. I really don’t know what to think I really have been trying for one and I just don’t want to get my hopes up just yet. That’s why I really need your help do you think I’m pregnant?

Please reply.
