Hey everyone.🥰 hope I can get some answers from all of you

I been on the pill for a few months now and for the first time my boyfriend came inside almost 4 weeks ago(period sex)when I’m not taking my pills just placebo ,and for several days now I been having morning sickness and some threw ups, and tender breast. Im supposed to have my period in one week and a half , is there any chance I’m pregnant?

So yesterday I was worried about maybe being pregnant so I looked up on internet about DIY homemade pregnancy test and I did the sugar one and I don’t know if that’s accurate but the sugar didn’t dissolve and was clumpy..

Also I have a 22-23 days cycle
