Need Advice.... Did I ovulate? Could I be pregnant?

My husband and I have been TTC for over a year now. For a long time I was not getting a regular period or ovulating on my own. However last March I found out my thyroid was not working correctly. Therefore my doctor and herbalist believe this is the reason my body wasn't working correctly.

Since then I got a period in May and in June. My period from May to June was 35 days. My period in June started in June 3rd and lasted until June 8th. Starting on June 19th (CD 17) I started tracking for ovulation using OPKs. I tested through June 24th (CD 22) and then I didn't track June 25th or 26th due to camping. On June 27th I had EWCM and my boobs were extremely swollen. However when I took a OPK it came up negative. Could I have surged on the 25th or 26th, but ovulated on June 27th?

On July 4th, 5th and 6th I felt as though I was getting my period. I was extremely irriatable and having anxiety plus feeling bloated. However today June 7th I don't have those symtoms (symptoms) as much and still no period. However I took a pregnancy test today and it was negative. However if I did ovulate around the 27th would it be too early to check for preganancy? If so, when would it probably show?

Any advice would be helpful, I am going nuts thinking about this? I really want to be pregnant, but realize I may not be.
