Super Early Ovulation?!

Mackenzie
Looking for opinions on whether or not I may have ovulated already? My cycles have been VERY irregular since coming off of BC in November (only had AF in January and now March) and I've never gotten a positive OPK until this cycle. I started OPKs the first day of no AF this time just to be thorough and ended up getting a strong positive one CD 6 and am still getting positives daily, even solid smileys on the digital. I plan to continue taking OPKs and temping through this cycle just to track even though I know you should stop OPKs after your first positive. It does look to me like I had a spike (0.4 degrees) on cd6 and it's stayed raised since but not sure if it really "counts" since it was directly after AF? Thanks for any input!
