Please Help!

Sorry for the long post ahead of time.....

My husband and I have been TTC for 2 years . We started fertility pills and i was on them for 2 months. On January 8th I got a very positive ovulation test and also felt some symptoms of ovulation. On January 12th I began to bleed a bit so I got discouraged . The blood was light pink and never filled a pad. It is not January 15th and I stopped bleeding this morning . I have had headaches, nausea , sore breasts , and cramps. I also smell things like sunflower seeds out of nowhere and for two days my mouth had a taste of metal in it .. can anyone help me ?? I’m not sure if it’s just my period or if I am pregnant ? I haven’t tested yet because I wasn’t sure if it’s too soon to or not ..
