Last period was April 25-28th, had unprotected May 1/2. Hubby came and surprised me a week early from work (He works in Alaska month on month off). So naturally we went out, toasted and whatever. I wasn't on anything because honestly I wasn'y exspecting him early and I was on some antibiotics for strep the monday prior so I know that can conflict with the bc so I didnt start it yet. Now, my calender says I was fertile the 4th-10 and I ovulated on the 9th. We only did the 1/2nd early morning and later that day. The last two days (a week after I took the plan B) my boobs are swollen and nipples super tender. Last time I remember this was when I was pregnant with our son. With him, I knew before the test did. I did take a test yesterday, negative but I know its too early since my next period isn't projected to start till the 23rd. We're good either way, personally I'd like to wait till it got cooler bc with my son, i was summer preggo and hated it. But if it happens it happens. Anyone else take the Plan B on the last day or a day later than supposed to?
