Any suggestions?

My husband and I have been trying to conceive our 2 cnd child for a couple years now but no luck. Finally, the past 2 1/2 months I haven’t got my period. I have taken 3 test the 1 st one came out positive and week later I took 2 more test that came out negative. I’ve been having pregnancy symptoms like constant running to the restroom, fatigue, sore breast, body aches, and sensitive to certain smells especially to perfumes and this has happen just in the past month. Do you think I can be pregnant? I’m scared to get my hopes up and take another test and get a negative. Any suggestions on what I should do? Or do you think I might already have a baby in my oven lol 🤞🤞🤞🤞🤞🤞🤞 fingers crossed I am !
