Pregnant?..

Slim
Ok so my cycle is usually from the 16th till the 23rd 7day process but it started on the 15th so I should have stopped on the 22nd but I took a shower and my partner found away to have sexual intercourse with me by the way was totally worth it.. so my cycle ended on the 19th a little early.Im currently waitin on the next one to come but I was told you can still receive your cycle while pregnant so I was wondering if I am?...😳
Also I took one test but there not always accurate the one I did take was positive😫
And I don't know how he would react if I told him I was because I have friends that's been in the same situation and the father was happy but when it was time he wasn't there.And I don't know  if I should tell him right away or?..How I should tell me..any ideas??🙄
Another question what if you do what to keep it but he decide that he's not ready and suggest abortion but your way against abortions how are you suppose to react or what conclusion can you try to make with that?😔
Thanks for your help and opinions😘
