Ok so a week ago around my cd 9, my husband had unprotected sex. I have been on the pill for a while. I was supposed to start my new pack last Sunday but kept forgetting and just thought I'll start it thr next day, no big deal. Well, Wednesday we had sex and took the first pill. By Friday, I was feeling slight cramps and did not have an appetite for a few days and was exhausted for no reason. For a few days I was going crazy thinking I was pregnant and just in case I stopped taking the pill. Today, I am having (TMI) some brown/red cm. now, I am really going crazy bc this usually doesn't happen even when I skip pills or change days that I start. I still have 2 weeks until my period....😁is it too soon to test? Thanks!!
