Hi, just recently I had sex with my boyfriend and first we used a condom but then the 2nd time that evening we didn't. Also to include I've been on birth control for about 3 years. First with depo then I had the paraguard iud implanted last august. I couldn't feel my strings after sex so I took a plan b pill about 24 hours later to be cautious. Later on after much curiosity I tried again to feel the strings bug went deeper to notice my strings are curled up but still there. Here it is day 3 and I'm experiencing whitish yellowish discharge. I've seen it before but it eventually stopped. I'm kind of worried about what my body is going through including back pain and the butterflies I'm feeling in my stomach.
It could be just anxiety because you was worried because you couldn't feel your strings or it could be just after effects me plan b, if it continues i would in get it checked out hun :-)
