Narrative:
Cleared for the ILS [runway] xxr and after trying to reach them twice and about 500-600 AGL; tower reported a windshear of -40 kts and I (pm) requested a go-around. At the same time that captain (PF) was calling 'go-around; set thrust; flaps 8;' tower gave the missed instructions of 4;000; localizer; 190 kts to which I responded the same. Somehow I missed captain make the go-around; thrust; flaps call and missed making my positive rate call out. When he made the call a moment later; I brought the gear up and flaps to 8. Somewhere around this time; I believe we encountered a negative performance microburst. We then encountered a rapid loss of airspeed that led to a stick shaker. After that I began calling out performance. At some point captain synced and selected the heading mode. I failed to catch that and we began to fly slightly north of the localizer. I then made a correction of the heading to return to the localizer either just before or just after tower asked us about the heading. Shortly after that; we were told to maintain current heading. At some point ATC made a call to which I responded that we had a warning and I'd get back with them in a moment. A bit later ATC called back to ask if we were ready for communications and gave us additional vectors and 5;000. After being vectored in and out of the localizer a couple of times; we were able to make the approach uneventfully about 30 minutes later.I can't help but think that the nearly 90 days I had not flown played a factor; but the fact is that I should have made the positive rate call and caught the selection of heading mode on the go-around.proactive self training:in the past I've recited 'go-around; set thrust; flaps 8' as a part of my approach briefing. I will now add the 'positive rate... Gear up' to that go-around brief to increase my chance of never missing the calls again.
