No one can tell you the odds of whether or not you will get pregnant. Also I think you will need to give some more info so we can help you better. When you say "fertility test" do you mean OPK? OPKs do not test for fertility, they test for lutenizing hormone which surges and helps the egg release from the follicle. You had an lh surge which means that you may ovulate 12-36 hours after the surge. If you do ovulate AND the sperm has good swimmers AND you have quality cervical mucous you will most likely have a 15-20% chance of conceiving this cycle. it is always good to have sex at least 2 times at your fertile window to make sure that swimmers get to where they need to go. Are you charting, temping, checking CM to ensure ovulation is actually happening? Also, you can have multiple lh surges in a cycle so this surge may not indicate O. FYI I had multiple lh surges after a progesterone withdrawal challenge and I was not ovulating.
I know I put a lot in my response but we really need some more info in order to best help you. Good luck and I will definitely check back in with you!
