HELP-HONEYMOOM SURPRISE

My husband and I just got back from our honeymoon late last night. (9/15) my ovulation week was 8/30-9/4. And we have had sex every day since then. before we left I purchased the Clear Blue digital tests. I'm supposed to get my period in 3 days, and told my husband I wanted to test. he insisted I wait until I had symptoms. Well last night and this morning I've had excruciating cramps. which I thought was strange because I don't normally get them with AF. so I woke at 6am, and tested. and there it was PREGNANT. My husband is still sleeping on the couch, and I want to tell him!! But I'm nervous a little bit, I've been off birth control for 2 months now, and we stopped using protection, so I'm wondering how far along I really am. although, we never had sex on ovulation days before. but I haven't had any symptoms prior. and I'm nervous after getting back from Mexico, and drinking...and getting bit by mosquitos any advic!?
