Implantion or af???

Okay ladies. Last month during ovulation I had sex on the highest day possible which was like 33.1% and then again after my ovulation period was over. Af showed up for October but it was really really light. I spotted for maybe 3 hours total within a 2 and 1/2 day time period. It was a really light pink color too. Then again this month I had sex 2 times a day during my highest chance of pregnancy. But here is my thing.... all week long I have wanted to sleep all day everyday. I've been really nausea, just the sight of my son flossing and brushing his teeth makes me want to vomit. I never take naps after 3pm and I laid down and took an hr nap tonite at 630. I know it's probably to early to test, but a part of every wants to test but I don't wanna do it and then be disappointed with a bfn. What would u do????
