hello, i started my birth control on jan 1st, but my fiance came inside me several times during the first week. there is a good chance that i was ovulating during this week, as the medicine had not yet had time to kick in. lately i have been very emotional, with sore breasts ocasionally, nausea, the munchies. I was supposed to start my period yesterday, but all i have had is a light pinkish color when i wipe with very slight cramps. i am constipated and very bloated, causing me to pee more than usual. What do you think my chances of actually being pregnant are? Should i take a test, or not worry about it?
