Had unprotected everyday day on may 8 10 12 15 17 19 20 22. Took ovulation test everyday starting on may 10 and was ovulating on may 20-21. I also had an ovarian cyst 8 months ago. Went to hospital with pain and they said my ovary burst on my left side. Didn't have surgery or nothing. Went to dr a week after and he said I had the cyst but it's gone. Can I still get pregnant? On ovulation day I had some lil cramps on my right side.could I be pregnant, if I am when will I get implantation bleeding? My stomach been felling lil crampy and last night it felt like I needed to throw up but I didn't. Let me know what you think please.
