I think I fucked up

Valentae

So I’ve been tryna to conceive for about 8 months , but these last few months I’ve been getting sick like vomiting and diarrhea and a few more symptoms and I have not been diagnosed yet , so because of that reason I decided to get on bc because I wasn’t feeling healthy enough to try to get pregnant . Any way I got off my period last week and the next day I started the bc I only took the bc pill for 2 days both days I was very sick vomiting and what not so I didn’t take them for 3 days and I feel fine but now I’m bleeding again !!! What’s does this mean did I fuck up my whole cycle ???
