I had been on the implanon NXT for a long time and because I was getting un normal pains in the lower belly area (on both sides) I took the implanon out and switched to the Levlen ed. I started taking the levlen a few days after I got the implanon out. I had sex two days before switching and ever since then I have been getting pregnancy symptoms A LOT lately.. My symptoms include: sore brests, heart burn, feeling the need to spew, fatigued, nauseous and a little spotting of blood but definitely not enough to be a period. I was just wondering could there be a possible chance I could be pregnant?
